Why do I need to use the three buffers in the Cell Fractionation Kit #9038?
Each buffer in the Cell Fractionation Kit #9038 contains detergents to help isolate different cellular fractions. The Cytoplasmic Isolation Buffer (CIB) contains a non-ionic deterg...
Can you provide data that confirms the specificity of your Raptor (24C12) Rabbit mAb #2280?
The specificity of our Raptor (24C12) Rabbit mAb #2280 has been confirmed by siRNA in the following papers:
PMID: 28648777 (https://pubmed.ncbi.nlm.nih.gov/28648777/) Figure...
How should I resuspend and aliquot the PTMScan® LysC Protease #84748?
To resuspend the PTMScan® LysC Protease #84748, we recommend allowing the vial to equilibrate at room temperature for a few minutes after removing from the -20C freezer. Next, ...
Do you have human-reactive antibodies available for SignalStar™ Multiplex IHC?
Yes, please select “Human” in the first step of the SignalStar Multiplex IH...
Can I use primers from the Illumina Nextera Library preparation system or design my own primers to amplify the DNA library generated from the CUT&Tag Assay Kit #77552??
Yes, you can use primers from the Illumina Nextera Library preparation system or self-designed primers to amplify the DNA library generated from the CUT&Tag DNA using the CUT&a...
How stable is the Senescence β-Galactosidase Staining Kit #9860 after multiple freeze/thaws?
We are confident that the Senescence β-Galactosidase Staining Kit #9860 will continue to perform as expected up to at least 3 freeze/thaw cycles. We recommend aliquoting your reage...
How are the SignalStar™ Multiplex IHC Kits & Reagents validated?
CST thoroughly validates each antibody available in the CST antibodies undergo thorough validation processes to ensure reliable performance for every approved application. This includes testing different protocol variations to identify ... The Concanavalin A beads can clump together rather easily, especially when the cells become lysed. To avoid this, make sure your cells are healthy and be sure to treat them very ge... We have several antibodies for detecting Akt phosphorylation at Ser473 that are validated for IHC-P with human samples. These are:
These synthetic peptides are recoverable using our immunoaffinity purification (IAP) antibody beads, and thus provide users with a measure of PTM... We have several antibodies for detecting β-actin that are validated for IF-IC with human samples. These include: The SignalStar Multiplex IHC kits and reagents have been optimized with respect to fluorophore pairing and order of antibodies. As tissues vary in quality and expression level of b... The VersicanG1-Fc (Rabbit IgG1) #15933 contained in the Hyaluronan Complete Tissue Staining Kit (HRP) #38822 and Hyaluronan Complete Tissue Staining Kit (Alexa Fluor® 488) #53721 h...
Can I modify the CST-recommended protocol for a given application?
Should I be concerned that my Concanavalin A beads "clump together" in some of my CUT&RUN experiments?
How does the specificity of the F(ab’)2 fragments differ from the corresponding full-length monoclonal antibodies?
Which phospho-Akt (Ser473) antibody do you suggest for paraffin-embedded immunohistochemistry (IHC-P) with human samples?
What is the intended use of the PTMScan® Control peptides?
Which β-actin antibody do you suggest for immunofluorescence-immunocytochemistry (IF-IC) in human samples?
Do I need to optimize the SignalStar™ Multiplex IHC Kits & Reagents for the type of tissue I’m using?
Is the VersicanG1-Fc (Rabbit IgG1) #15933 product homologous with all species?
