Anti-Neu5Gc Antibody Kit Protocol - Western Blot Resource Report Resource Website |
Kelsey Miller | DOI:10.17504/protocols.io.hvrb656 | BioLegend | The Anti-Neu5Gc Antibody Kit contains the essential monospecific polyclonal chicken IgY antibody, along with a negative control primary antibody to detect the presence of Neu5Gc on glycoconjugates by Western blot (WB). Samples to be evaluated are first subjected to SDS-PAGE, followed by transfer to a nitrocellulose or polyvinylidenedifluoride (PVDF) membrane. The membrane is then incubated with affinity-purified polyclonal anti-Neu5Gc to determine the presence of Neu5Gc on the protein of interest.The antibody provided in this kit has been shown to identify as little as 5 pmol of Neu5Gc per ug glycoprotein, which is at or below the current detection limit for conventional analysis by acid release, purification, DMB derivatization, HPLC, and electrospray mass-spectrometry. The Western blot provides additional information in that it confirms that Neu5G is directly linked to the glycoprotein of interest rather than to an accompanying sample component. | BioLegend | http://www.biolegend.com/media_assets/support_protocol/Neu5Gc_Antibody_Kit_Protocols_110813.pdf | 2 | 2017 | Kelsey Miller 2017.

MARVICS: A Robust and Safe Magnetic Nanoparticle based RNA Extraction Method Compatible with Phenol-chloroform Inactivated Infectious Samples Resource Report Resource Website |
Mo Li, Gerardo Ramos-Mandujano | DOI:10.17504/protocols.io.bik4kcyw | Diagnosis and surveillance of emerging pathogens such as SARS-CoV-2 depend on nucleic acid isolation from clinical and environmental samples. Under normal circumstances, samples would be processed using commercial proprietary reagents in Biosafety 2 (BSL-2) or higher facilities. A pandemic at the scale of COVID-19 has caused a global shortage of proprietary reagents and BSL-2 laboratories to safely perform testing. Therefore, alternative solutions are urgently needed to address these challenges. We developed an open-source method called Magneticnanoparticle-Aided Viral RNA Isolation of Contagious Samples (MAVRICS) that is built upon reagents that are either readily available or can be synthesized in any molecular biology laboratory with basic equipment. Unlike conventional methods, MAVRICS works directly in samples inactivated in acid guanidinium thiocyanate-phenol-chloroform (e.g., TRIzol), thus allowing infectious samples to be handled safely without biocontainment facilities. | King Abdullah University of Science and Technology, Laboratory of Stem Cell and Regeneration, Biological and Environmental Science and Engineering Division, King Abdullah University of Science and Technology (KAUST) | https://www.medrxiv.org/content/10.1101/2020.06.28.20141945v1 | 2 | 2020 | Mo Li, Gerardo Ramos-Mandujano 2020.

PCR amplification and restriction fragment length polymorphism analysis of four SNPs (C5178A, A10398G, G13708A, and C13928G) in the mtDNA coding region Resource Report Resource Website |
Feng-ling Xu; Mei Ding; Jun Yao; Zhang-sen Shi; Bao-jie Wang | DOI:10.17504/protocols.io.ipgcdjw | The four SNPs (C5178A, A10398G, G13708A, and C13928G) in the mtDNA coding region were detected using PCR-RFLP analysis. The primers listed in able 2 were used to amplify target fragments. The mismatch method was applied to generate an HpyCH4Ⅲ artificial restriction endonuclease site in the amplified fragment that included the C13928G SNP. The 20 µl PCR reactions contained 2.0 µl 10×buffer, 2 µl 2.5 mM dNTP mix, 2 µl each of R and F PCR primers (10pM each), 0.2 µl of rTaq Enzyme (5 U/µl), and 20 ng of template DNA. PCR was performed under the following cycle conditions: initial denaturation of 94 °C for 5 minutes; followed by 30 cycles of 94 °C denaturation for 30 seconds, annealing at 61-65°C (Table 2) for 30 seconds, and elongation at 72 °C for 30 seconds; followed by a final extension at 72 °C for 5 minutes. PCR products were digested with restriction enzymes (S1 Table), and fragments were detected on 6% polyacrylamide gel. A1Table 2.

Sam Li | DOI:10.17504/protocols.io.babeiaje | BioLegend | Using UV-induced peptide exchange, MHC/peptide monomers can be generated with conditional Flex-T™ monomers that harbor peptides of interest in their binding grooves. These new MHC monomers are subsequently multimerized using streptavidin-fluorophore conjugates. The resulting Flex-T™ reagents can be used for staining antigen-specific T cells and flow cytometric analysis. In humans, the MHC molecules are called HLA (Human Leukocyte Antigen). | BioLegend | https://www.biolegend.com/protocols/flex-t-tetramer-preparation-and-flow-cytometry-staining-protocol/4251/ | 3 | 2019 | Sam Li 2019.

Bioorthogonal Noncanonical Amino Acid Tagging (BONCAT) incubation - ROCKS Resource Report Resource Website |
Jackie Goordial | DOI:10.17504/protocols.io.utkewkw | Orcutt Deep Biosphere Lab | BONCAT is a technique that allows for the visualization and isolation of metabolically active cells from complex environmental enrichments. This is achieved by incubating a sample with synthetic methionine analogs AHA (l-azidohomoalanine) or HPG (l-homopropargylglycine). Instead of the sulfhydryl side group of methionine , these analogs contain an azide or alkyne functional group, respectively, which can be chemically tagged with a fluorophore using a process termed “click-chemistry”. Throughout the incubation period actively growing cells incorporate these synthetic amino acids into newly synthesized proteins. After harvesting cells from a live enrichment, the cells are tagged with the fluorophore. This allows for microscopic visualization along with FACS-based isolation of the metabolically active cells in a community. Downstream analysis can include single-cell sequencing or metagenomics techniques to determine taxonomy and functions of isolated organisms. Notes: Working with low-biomass samples has an inherent high-risk of contamination. Be mindful of sterility at all times. Perform all work in the biological safety cabinet and make sure to sterilize the hood with UV prior beginning work Some of the BONCAT reagents are light-sensitive, be careful to pay attention to if a particular step in the protocol needs to be performed in the darkThe click-chemictry reaction is very sensitive to oxygen, so take care not to vortex/ introdroduce air unnecessarily Try to plan when you harvest incubations so that you are certain you will be able to perform the click-chemistry process the next morning | orcutt lab protocols | 1 | 2018 | Jackie Goordial 2018.

Immunoblot based assay for simultaneous densitometric determination of ubiquitin forms in Drosophila melanogaster Resource Report Resource Website |
Ágota Nagy, Levente Kovács, Zoltán Lipinszki, Margit Pál, Péter Deák | DOI:10.17504/protocols.io.s5teg6n | This protocol describes an immunoassay, originally developed to quantitate ubiquitin in mouse tissues (Oh et al., Anal. Biochem. 443, 153–155), which we adapted to Drosophila melanogaster. The method is suitable for the simultaneous determination of total, free and conjugated ubiquitin forms from whole protein extracts by densitometric analysis of Western blots. In this assay, endogenous deubiquitylating enzymes, DUBs, present in the lysates process all conjugated ubiquitins to monoubiquitins, therefore the total ubiquitin content of cell lysates can be determined in the form of monoubiquitins. The free monoubiquitin fraction in turn is determined from similar lysates, but supplemented with a potent DUB inhibitor, NEM. Appropriate samples of these lysates are immunoblotted together with ubiquitin standards that allow the quantification of the different ubiquitin forms by densitometric analysis of the 8,5 kDa monoubiquitin band. | Department of Genetics, University of Szeged, Szeged, Hungary, Department of Genetics, University of Szeged, Szeged, Hungary, Institute of Biochemistry, Biological Research Centre, Szeged, Hungary, Institute of Biochemistry, Biological Research Centre, Szeged, Hungary, Department of Genetics, University of Szeged, Szeged, Hungary | 1 | 2018 | Ágota Nagy, Levente Kovács, Zoltán Lipinszki, Margit Pál, Péter Deák 2018.
