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, ...
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...
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...
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...
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 are the SignalStar™ Multiplex IHC Kits & Reagents validated?
CST thoroughly validates each antibody available in the 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 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 caspase-3 when cleaved at Asp175 that are validated for IHC-P with mouse samples. These are:
Do I need to optimize the SignalStar™ Multiplex IHC Kits & Reagents for the type of tissue I’m using?
Should I be concerned that my Concanavalin A beads "clump together" in some of my CUT&RUN experiments?
Which cleaved caspase-3 (Asp175) antibody do you suggest for paraffin-embedded immunohistochemistry (IHC-P) with mouse samples?
Can I reuse PTMScan® antibody beads?
The “classic” PTMScan® kits that use agarose beads and the PTMScan HS kits that use magnetic beads are both designed for a single PTM peptide enrichment. The nature of the acidic e...
Which cleaved caspase-3 (Asp175) antibody do you suggest for paraffin-embedded immunohistochemistry (IHC-P) with human samples?
We have several antibodies for detecting caspase-3 when cleaved at Asp175 that are validated for IHC-P with human samples. These are:
- Cleaved Caspase-3 (Asp175) Antibody #9...
Which phospho-Akt (Ser473) antibody do you suggest for Immunofluorescence (Immunocytochemistry) (IF-IC) with human samples?
We have several antibodies for detecting the phosphorylation of Akt at Ser 473 that are validated for IF-IC with human samples. These include the following:
- Phospho-Akt (Se...
Is the VersicanG1-Fc (Rabbit IgG1) #15933 product homologous with all species?
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...
Have species been tested if they are not listed as cross-reactive with a CST antibody on the datasheet?
Possibly. CST scientists test all our antibodies on multiple species when feasible, depending on the target protein and the experimental systems available. If a tested species does...
