G-Biosciences DOI:10.17504/protocols.io.e4bbgsn G-Biosciences For routine protein assays, we recommend that researchers generate their own CB-X™ Tables or standard curves. This is a one time commitment to ensure user specific results and allows single tube assays to be performed each time as opposed to generating new calibration plots for each assay. We recommend using a protein standard similar to you protein of interest or a purified source of your protein.The supplied CB-X™ tables may result in some inconsistencies due to the type of cuvettes or microtiter plates used. CB-X™ Table for Spectrophotometer readings were measured with 1cm path length cuvettes against deionized water and CB-X™ Table for Microplate Reader readings were measured using Nunc™ Immuno 96 MicroWell™ Plates (MaxiSorp™ ) [Cat# 442404] against deionized water. http://www.gbiosciences.com/PDF/Protocol/CB-X_Protein_Assay.pdf 1 2016 G-Biosciences 2016.

Changes in spinal stiffness with chronic thoracic pain: correlation with pain and muscle activity
 
Resource Report
Resource Website
Isabelle Pagé, François Nougarou, Arnaud Lardon, Martin Descarreaux DOI:10.17504/protocols.io.twwepfe The main goal of this project is to assess the reliability of thoracic spinal stiffness. To achieve this, 25 heartily participants (no significant thoracic pain in the past year) and 25 participants with chronic thoracic pain will participate in 2 experimental sessions separated by 24 to 48 hours. These sessions will occur at the Neuromecanic and Motor Control Laboratory of the Université du Québec à Trois-Rivières (Trois-Rivières, Québec, Canada). During these sessions, spinal stiffness will be measured at four thoracic spinal levels (T5 to T8) in a randomized sequence via a mechanical device using a servo-linear motor. The device indenter (metallic cylindrical cover with a rubber of 2 cm diameter) will gradually apply 45 N to the spinous process. The muscle activity and displacement data will be recorded during the procedures.

Detection of single nucleotide polymorphisms with padlock probes
 
Resource Report

Tomasz Krzywkowski, Mats Nilsson DOI:10.17504/protocols.io.wjhfcj6 Molecular Diagnostics - Mats Nilsson Group, Neurodegeneration Method Development Community This protocol is for in situ detection of mRNAs and single nucleotide polymorphisms using padlock probes and rolling circle amplification. In the accompanying publication, we take advantage of a single nucleotide variant within conserved ACTB mRNA to successfully differentiate human and mice co-cultured cells and apply following protocol to genotype PCDH X and Y homologs in human brain tissue sections. These are used as examples in the accompanying publication and custom padlock probes can be designed to allow for the targeting of own desired mRNA. We provide a method for automated characterization and quantitation of target mRNA in single cells or chosen tissue area. mRNA of interest, harboring a polymorphism, is first reverse-transcribed to cDNA. Allele specific padlock probes are hybridized to the cDNA target and enzymatically circularized maintaining a physical link with the parent mRNA molecule. Lastly, circularized probes are replicated in situ, using rolling circle amplification mechanism to facilitate detection.This protocol is taken directly from the accompanying publication. Further details and background information can be found in the cited published article.

Recombinant Protein Expression of MMLV-RT H+ (SkiBar H+ RT) V2
 
Resource Report

Alex Brown DOI:10.17504/protocols.io.bijzkcp6 Reclone.org (The Reagent Collaboration Network) About:This protocol has been optimized for recombinant expression of molony virus based reverse transcriptases (RT). The plasmid used contains a reverse transcriptase gene which is derived from Moloney Murine Leukemia Virus. The enzyme when expressed recombinantly can synthesizes a complementary DNA strand from single-stranded RNA, DNA, or an RNA:DNA hybrid.Enzyme Engineering:The enzyme contains point mutations to generate a highly processive, thermostable, and improved fidelity mutant reverse transcriptase. Details, incluiding the sequence of this enzyme are published and can be found in the references below and addgene link. The enzyme contains an active RNAse H domain and is highly thermostable. This MMLV construct contains the following mutations: D200N, L603W, T330P, L139P, E607K,D524G, E562Q, D583N and D653N. These appear to be the same set of mutations present in the Thermo Fisher Maxima H- RT, which is one of the best preforming RTs you can buy. The enzyme in our hands is extremely active. Moreover, while the MMLV RT is thermostable and will work up to 65°C it runs optimally at 42°C.The point muitations utilized here are currently filed under a provisional patent with Thermo Fisher Scientific. Commcercial use of this enzyme must go though Thermo Fisher Scientific.It is also possible to further engineer this enzyme with to increase thermostability and eliminate RNase H activity to generate an enzyme which closely mimicks Thermo Fisher Maxima H+ RT.Introducing mutations (D524G, E562Q, D583N and D653N) and/or (D524, D583, E562, H204, V223, T306, F309) are best suted eliminate RNase H activity completely, and it will increase the thermostability somewhat as wellComments:Reference 2 highlights several point mutations which can be introduced to eliminate Rnase H activity which may also enhance RT sensitivity. Thermo Product information brochure from 2013 suggest that this mutant or some combintation of other identified point mutations from reference 2 is Maxima RT, Maxima H-. The paper has also identified a few more useful point mutations which may further optimise MMLV-RTThis expression protocol can also implemented to express other MMLV based reverse transcriptases or diversely related retroviral RTs, provided the genes are in an expresison construct with an N- terminal 6-10 His Tag and are expressed under a T7 promoter.The plasmid used can be found on reclone.org and addgeneSkiBar H+ RT was synthesized as a gBlock from IDT and is codon optimized. Expressed in Rosetta DE3 his tag is on still but seems to work fine with it on.Tgatcc motif at MCS is a result of issues cloning in with BamHI.
