pCAF (P300/CBP-associated factor, EC also known as K (lysine) acetyltransferase 2B (KAT2B), possesses intrinsic histone acetyltransferase (HAT) activity. pCAF contributes to transcriptional activation by acetylating chromatin and transcription factors through its HAT activity. Deregulated HAT activity plays an important role in various cancers. pCAF inhibitors have potential applications in cancer therapy. pCAF uses both histone 3 (H3) and histone 4 (H4) as substrates. BioVision’s pCAF Inhibitor Screening Kit utilizes H3 peptide and Acetyl CoA as the substrates. pCAF acetylates the peptide and generates Coenzyme A with a free thiol group. The CoA is detected using a Thiol Detecting Probe that reacts with thiol groups and gives enhanced fluorescence that can be measured at Ex/Em = 392/482 nm. In the presence of pCAF specific inhibitors, the enzymatic activity is inhibited resulting in decreased or total loss of fluorescence. This assay kit is a simple, sensitive, and rapid tool to screen potential pCAF inhibitors.

Can the kit work on bacteria or yeast cells?
The kit has been standardized for mammalian cells only
What is the exact volume of sample required for this assay?
There is no specific volume we can recommend for the amount any sample to be used since it is completely sample concentration and quality based. You have to do a pilot expt with multiple sample volumes to determine the optimal volume which gives a reading within the linear range of the standard curve. Please refer to the citations for this product to see what other clients have used with similar sample types.
Do you have trial sizes of this kit?
Unfortunately, we do not have trial sizes of this kit available. However, if you are based in the US or Canada, we will give you a 10% off list price introductory discount on its purchase price. If you are based out of this area please contact your regional BioVision distributor.
Can we purchase individual components of this kit?
Yes, you can purchase any of the kit's components without the whole kit. Please refer to the component Cat #s mentioned on the datasheet for ordering.
Can we use an alternate buffer for sample preparation (cell lysis, sample dilutions etc)?
Our assay buffers are optimized for the reactions they are designed for. They not only contain some detergents for efficient lysis of your cells/tissue, but also contain some proprietary components required for the further reactions. Therefore, we highly recommend using the buffers provided in the kit for the best results.
