Biochemical Measures of Neuropathy - Western Blot Stripping Resource Report Resource Website |
Eva Feldman | 10.17504/protocols.io.3s3gngn | Diabetic Complications Consortium | Summary:Oxidative stress is highly correlated with the metabolic changes caused by hyperglycemia. Increased levels of glucose overload mitochondria and result in the production of reactive oxygen species (ROS). In addition, the flow of excess glucose through cellular pathways decreases the cell’s normal ability to detoxify ROS. As a result, the neurons and axons of the peripheral nervous system contain increased levels of ROS and decreased antioxidant capacity. The following assays are used to measure these changes in rodent models of diabetic neuropathy.

Distribution of aerophilous diatom communities associated with terrestrial green macroalgae in the South Shetland Islands, Maritime Antarctica - PROTOCOL Resource Report Resource Website |
Juliana Ferreira da Silva, Maria Angélica Oliveira, Raylane Ribeiro Anunciação, Eduardo Pereira da Silva, Rodrigo Paidano Alves, Adriano Luis Schunemann, Filipe de Carvalho Victoria, Margéli Pereira de Albuquerque, Antonio Batista Pereira | 10.17504/protocols.io.6tcheiw | The establishment of diatom communities depends on environmental factors such as the type of substrate and geographic conditions that influence the dispersal processes of these organisms. The main goal of this study was to evaluate the similarity between diatom communities associated with the macroalgae Prasiola crispa(Lightfoot) Kützing in relation to spatial distance from six sampled sites located in the South Shetland Islands, Maritime Antarctica. The diatom flora associated with Prasiola crispawas represented by 23 species distributed in 15 genera. Pinnularia australoschoenfelderiZidarova, Kopalová & Van de Vijver, LuticolaaustroatlanticaVan de Vijver, Kopalová, S.A.Spaulding & Esposito, Luticolaamoena Van der Vijver, Kopalová, Zidarova & Levkov, Pinnularia austroshetlandica(Carlson) Cleve-Euler and Psammothidium papilio(D.E. Kellogg et al.) Kopalová & Zidarova were the most abundant species in our samples, which together represented 68% of the total number of individuals collected. There is a great similarity in composition and abundance of the diatom community among the sampled points., which resulted in the absence of a linear pattern of relationship with the distance between sampling points. We conclude that distance was not a factor of differentiation of Antarctic diatom communities associated with terrestrial green macroalgae. Suggesting that Antarctic environments may have unique characteristics with homogeneous abiotic factors, at least related to this substrate. | Silva JFd, Linton MAO, Anunciação RRd, Silva EPd, Alves RP, Schünemann AL, Victoria FdC, Albuquerque MPd, Pereira AB (2019) Distribution of aerophilous diatom communities associated with terrestrial green macroalgae in the South Shetland Islands, Maritime Antarctica.

Troubleshooting biGBac: a practical guide Resource Report Resource Website |
Erin Cutts, Alessandro Vannini | 10.17504/protocols.io.q3ydypw | The biGBac system presented by Weissmann et al. (Weissmann et al, 2016 and Weissmann et al, 2018) is a modular insect cell expression system designed for expression of multi-subunit complexes. The system is very powerful, allowing up to 25 genes to be assembled into one baculo-virus expression vector, but does require a reasonable amount of cloning experience in order to attain clones in the 6 day time frame stated in the paper. This guide was written to provide a detailed explanation how the system is designed, how it can be further exploited and provide in-depth practical information that even a novice cloner can follow. | the Institute of Cancer Research, the Institute of Cancer Research | 1 | 2018 | Erin Cutts, Alessandro Vannini 2018.

OnsiteGene 1 Protocol Nasal Direct Resource Report Resource Website |
yliu | 10.17504/protocols.io.bkudkws6 | OnsiteGene 1, XPRIZE Rapid Covid Testing | This OnsiteGene protocol is designed for testing the nasal swab samples without nucleic acid extraction. It uses the Star Array® Hi-SenseTM COVID-19 Molecular Testing Kit 1.0 in the one-step real-time RT-qPCR test assay to qualitatively detect RNA from SARS-CoV-2 virus in the human respiratory specimen. It combines the reverse transcription technology and real-time PCR method to provide accurate detection of the SARS-CoV-2 coronavirus. Along with the Star Array® SATM Direct Extract Buffer, the protocol supports direct amplification without the need of specific RNA extraction equipment and kit. It significantly reduces the loss of RNA from the sample extraction and purification process, saves time and workload from sample preparation, and minimized the burdens on supply chain. The triplex fluorescence design of the kit simultaneously detects the N1 and Orf1ab genes of the virus and the human RNase P gene as an internal control to ensure the sample quality. This protocol uses the Star Array® XDiveTM Superfast Real-Time RT-qPCR instrument to perform 40-cycle PCR in 8 minutes, and can test up to 16 samples or controls in each run. The total protocol time from sample collection to data interpretation is less than 11 minutes. | OnsiteGene Inc. | 1 | 2020 | yliu 2020.

RNA Sequencing of Porine Ganglia and brainstem Resource Report Resource Website |
Leah Reznikov | 10.17504/protocols.io.w5sfg6e | SPARC | RNA Sequencing of Porine Ganglia and brainstem Animals. A total of 44 piglets (Yorkshire Landrace breed, 2–3 days of age) were fed commercial milk replacer (Soweena Litter Life) and allowed a 36–48-h acclimation period before interventions began. The University of Florida Animal Care and Use Committee approved all procedures. Procedures were completed in accordance with federal policies and guidelines. A total of 12 piglets were reserved for RNA sequencing experiments (6 male and 6 female). Airway instillation. After acclimation, piglets were anesthetized with 8% SevoThesia (Henry Schein). The piglets’ airways were accessed with a laryngoscope; a laryngotracheal atomizer (MADgic) was passed directly beyond the vocal folds, as previously described to aerosolize either a 500 μl 0.9% saline control or 1% acetic acid in 0.9% saline solution to the airway. This procedure results in widespread distribution of aerosolized solutions throughout the piglet airway, including the lung. Consistent with acid as a cough-evoking stimulus acetic acid induced cough in 90% or greater of the piglets. Nodose ganglia and brain stem isolation. Forty-eight hours after instillations, piglets were euthanized with a 90 mg/kg intravenous Euthasol solution (Henry Schein). Nodose ganglia were carefully dissected using methods that we previously developed. Ganglia were removed, placed in TRIzol, and stored at −80°C until RNA extraction. Any connective tissues, inflammatory cells, satellite cells, or blood cells covering the ganglia were not removed. A region of the brain stem encompassing the nucleus tractus solitarius, nucleus ambiguous, and dorsal motor nucleus was removed. Briefly, a blunt scissor was used to cut through the sagittal suture of the skull post mortem, and the brain was delicately excised. The cerebellum was removed, and the obex was identified. A section of the brain stem encompassing 2 mm rostral and 2 mm caudal to the obex was then removed and placed in RNAlater (Thermo Fisher Scientific). The block was further trimmed to extend 2 mm in depth and 2 mm lateral from the obex, while still submerged in RNAlater. RNA isolation. RNA from thenodose ganglia, and brain stem were isolated using RNeasy Lipid Tissue kit (Qiagen) with optional DNase digestion (Qiagen). RNA concentrations were assessed using a NanoDrop spectrophotometer (Thermo Fisher Scientific). RNA sequencing. RNA concentration was determined on Qubit 2.0 Fluorometer (ThermoFisher/Invitrogen), RNA quality was assessed using the Agilent 2100 Bioanalyzer (Agilent Technologies). Total RNA with 28S/18S > 1 and RNA integrity number (RIN) ≥ 7 were used for RNAseq library construction. RNAseq library were constructed using NEBNext Ultra Directional RNA library prep kit for Illumina (New England Biolabs) following the manufacturer’s recommendations. Briefly, 1,000 ng of total RNA was used for mRNA isolation using NEBNext Ploy(A) mRNA magnetic isolation module (New England Biolabs, cat. no. E7490). RNA library construction was achieved using NEBNext Ultra Directional RNA library prep kit for Illumina (New England Biolabs; cat. no. E7420). Thirty-six barcoded libraries were sized on the bioanalyzer and quantitated by QUBIT. Libraries were pooled in an equimolar ratio and sequenced by Illumina HiSeq 3000 2X100 cycles run for total of six runs (Illumina). RNA library construction was performed at the Interdisciplinary Center for Biotechnology Research (ICBR) Gene Expression & Genotyping Core, University of Florida (UF). HiSeq 3000 sequencing run was performed at the ICBR NextGen DNA Sequencing core, UF. The nodose ganglia and brain stem of three individual piglets for each condition were prepared separately and used. Mapping and differential gene expression. The quality of the RNA-Seq sequence data was first evaluated using FastQC before further downstream analysis. Low-quality sequences were removed, and the poor-quality part of the reads were trimmed using Trimmomatic. Star Aligner was used to map high-quality paired-end reads to Sus scrofa genome, Sscrofa11.1. Expression was obtained using RSEM. The expected read counts and fragments per kilobase of transcript per million-mapped reads (FPKM) were extracted for further analysis. The estimated read counts were taken as input for edgeR to perform differential expression analysis using generalized linear models. The threshold for calling significantly differentially expressed genes was set at FDR 0.05 with the average FPKM for at least one of each comparison group being higher than 0.

His-tag purification Resource Report Resource Website |
Andreea S | 10.17504/protocols.io.bnw5mfg6 | iGEM Groningen 2020 | His tag purification uses the technique of immobilised metal affinity chromatography. In this technique, transition metal ions are immobilized on a resin matrix using a chelating agent such as iminodiacetic acid. It has been studied that among amino acids constituting proteins, histidine is strongly involved in the coordinate bond with metal ions. Therefore, if a number of histidines are added to the end of the protein by genetic engineering, the affinity of the protein for the metal ion is remarkably increased and the basic idea is that purification can be easily carried out. When a protein having a His tag is brought into contact with a carrier on which a metal ion such as nickel is immobilized, the histidine residue chelates the metal ion and binds to the carrier. Since other proteins do not bind to the carrier, they can be washed off with a buffer. Thereafter, it is possible to recover the protein having the His tag with high purity. | University of Groningen | 1 | 2020 | Andreea S 2020.

If you want to find a specific protocol and you know the DOI of the protocol already, it's easier to enter a DOI to search. You can refine the search results using Facets on the left side of the search results page. If you are on the table view, you can also search in a specific column by clicking the column title and enter the keywords.
If you still could not find your protocol in the search results, please help us by adding it into the system — it's easy. Create and publish your protocols at Protocols.io.
