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&Tag Assay Kit #77...
Do you have human-reactive antibodies available for SignalStar™ Multiplex IHC?
Yes, please select “Human” in the first step of the SignalStar Multiplex IHC Panel Builder ...
How are the SignalStar™ Multiplex IHC Kits & Reagents validated?
CST thoroughly validates each antibody available in the 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 detergent used as a cell p... 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 reagents into single use ... 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 biomarkers, increasin... We have several antibodies for detecting β-actin that are validated for IF-IC with human samples. These include: Why do I need to use the three buffers in the Cell Fractionation Kit #9038?
How stable is the Senescence β-Galactosidase Staining Kit #9860 after multiple freeze/thaws?
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?
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 elution step, which l...
Which cleaved caspase-3 (Asp175) antibody do you suggest for paraffin-embedded immunohistochemistry (IHC-P) with mouse samples?
We have several antibodies for detecting caspase-3 when cleaved at Asp175 that are validated for IHC-P with mouse samples. These are:
- Cleaved Caspase-3 (Asp175) Antibody #9661
- Cleaved ...
How does the specificity of the F(ab’)2 fragments differ from the corresponding full-length monoclonal antibodies?
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 gently during the cell...
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 mAbs from multiple clon...
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 has been tested succe...
Why is the concentration of my antibody so low?
At CST, our antibodies are formulated on the basis of their reactivity and performance for each approved application at a recommended dilution. For antibodies with high affinity, optimal performan...
Can I order a custom formulation of an antibody?
For custom (carrier-free) orders, many antibodies are available pre-formulated in PBS without BSA or glycerol. This carrier-free formulation is amenable to conjugation and can be conjugated to fluorop...
