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

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...

When comparing my SignalStar™ staining to the chromogenic staining on a serial section, I see more positive cells. 我如何知道这种过度染色是否正确?

在优化过程期间,我们已发现荧光染色可能比生色性染色显示更高的阳性%。To ensure any excess staining is specific, confirm that the correct sub...

我是否应该担心我的 Concanavalin A 磁珠在我的一些 CUT&RUN 实验中“聚集在一起”?

Concanavalin A 磁珠可以很容易地凝集在一起,尤其是在细胞裂解时。To avoid this, make sure your cells are healthy and be sure to treat them very gently during the cell...

How long after the completion of staining can I wait to image my slides when performing a SignalStar™ Multiplex IHC assay?

对于第 1 轮成像,在完成染色后 8 小时内成像时,染色应显示稳定信号。For Imaging Round 2, imaging should be performed as close to the completion of staini...

您的 CUT&RUN 分析试剂盒是否适用于分离的胞核?

我们的 CUT&RUN 检测试剂盒经过优化,适用于整个细胞,并且适用于大量细胞系,包括贴壁和悬浮细胞。While it is not typically necessary to pre-isolate cell nucle...

Is PTMScan® compatible with SILAC?

PTMScan® is compatible with the use of stable isotope labeling using amino acids in cell culture, or SILAC. The incorporation of heavy stable isotopes has no effect ...

What is the species reactivity of the SUMO remnant PTMScan® kits that utilize WaLP for peptide digest?

野生型 α-裂解型蛋白酶 (WaLP) 是一种丝氨酸肽链内切酶,这种酶会裂解丙氨酸、丝氨酸、苏氨酸和缬氨酸等氨基酸的羧基末端侧。

WaLP recognizes and cleaves SUM...

What is the best way to choose an antibody for my CUT&RUN assay if I cannot find a CUT&RUN validated antibody for my target protein?

When selecting an antibody for use in CUT&RUN, we recommend starting with a ChIP or ChIP-seq-validated antibody; however, we have found that not all ChIP-validated antibodies work in the CUT&am...

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 reagents into single use ...

What is an appropriate positive control to include in this SignalStar™ assay? 是否需要多个对照?

Any tissue shown to be positive for each marker via chromogenic IHC can serve as a positive control tissue for a SignalStar™ assay. Each target will therefore require a positive control, which may som...

Do you have mouse-reactive antibodies available for SignalStar™ Multiplex IHC?

Yes, please select “Mouse” in the first step of the SignalStar Multiplex IHC Panel Builder ...

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...

My items say to store at -20°c but they were shipped in an envelope. Is it ok to use?

Yes, it is safe to use these items. Since 2003, CST has been shipping antibodies at room temperature when possible to reduce waste from packing materials. All CST antibodies are stability tested by ex...
