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, ...
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...
Do you have human-reactive antibodies available for SignalStar™ Multiplex IHC?
Yes, please select “Human” in the first step of the SignalStar Multiplex IH...
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...
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 do the Phospho-Tyrosine Mouse mAb (P-Tyr-100) #9411 and the Phospho-Tyrosine (P-Tyr-1000) MultiMab™ Rabbit mAb mix #8954 compare in terms of their sensitivity and specificity?
The Phospho-Tyrosine Mouse mAb (P-Tyr-100) #9411 is a mouse mAb from a single clone, whereas the Phospho-Tyrosine (P-Tyr-1000) MultiMab™ Rabbit mAb mix #8954 is a mix of rabbit mAb...
How does the specificity of the F(ab’)2 fragments differ from the corresponding full-length monoclonal antibodies?
Does CUT&RUN show a bias toward euchromatin or heterochromatin?
We do not observe any bias toward euchromatin or heterochromatin in our assays. In CUT&RUN, the target-specific antibody recruits the pAG-MNase and directs digestion to chromat...
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 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... We have several antibodies for detecting β-actin that are validated for IF-IC with human samples. These include:
Can I modify the CST-recommended protocol for a given application?
Do I need to optimize the SignalStar™ Multiplex IHC Kits & Reagents for the type of tissue I’m using?
Which β-actin antibody do you suggest for immunofluorescence-immunocytochemistry (IF-IC) in human samples?
Should I be concerned that my Concanavalin A beads "clump together" in some of my CUT&RUN experiments?
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...
