Tested Applications

• Positive WB detected in: HeLa cells, Jurkat cells
• Positive IHC detected in: human prostate cancer tissue; Note: suggested antigen retrieval with TE buffer pH 9.0; (*) Alternatively, antigen retrieval may be performed with citrate buffer pH 6.0
• Positive IF detected in: HeLa cells

Recommended dilution

• Western Blot (WB): WB : 1:1000-1:4000
• Immunohistochemistry (IHC): IHC : 1:150-1:600
• Immunofluorescence (IF): IF : 1:400-1:1600

It is recommended that this reagent should be titrated in each testing system to obtain optimal results.

Background Information

The acetyltransferase CREB-binding protein (CREBBP; also known as CBP or KAT2A) and E1A-binding protein P300 (EP300; also known as P300 or KAT2B) are two closely related regulators. Both are widely expressed within and outside the hematopoietic system and serve as tumor activators or suppressors depending on the situation. CREBBP/EP300 regulate various key physiological functions, including cell apoptosis, proliferation and differentiation, DNA repair, and somatic cell reprogramming.
