General notes
The Life Science industry has been in the grips of a reproducibility crisis for a number of years. Abcam is leading the way in addressing the problem with our range of recombinant monoclonal antibodies and knockout edited cell lines for gold-standard validation.
One factor contributing to the crisis is the use of antibodies that are not suitable. This can lead to misleading results and the use of incorrect data informing project assumptions and direction. To help address this challenge, we have introduced an application and species grid on our primary antibody datasheets to make it easy to simplify identification of the right antibody for your needs.

Primary antibody notes
Cyclic AMP-responsive enhancer binding protein (CREB) binding protein (CBP) and p300 are closely related transcriptional coactivators that have been shown to directly interact with many different DNA-binding transcription factors including nuclear hormone receptors, CREB (cyclic AMP-responsive enhancer binding protein), c-Fos, c-Jun/v-Jun, c-Myb/v-Myb, TFIIB and MyoD.Both CBP and p300 have been shown to display histone acetyltransferase (HAT) activity, capable of acetylating all four core histone particles in nucleosomes.As a result of HAT activity, it has been suggested CBP and p300 may play a direct role in activating chromatin for transcription.Single point mutations in CBP have been proposed as causative factors in the developmental abnormalities of Rubinstein-Taybi syndrome (RTS).Although both CBP and p300 appear to function similarly, the inability of p300 to rescue CBP malfunction iRTS suggests intrinsic functional differences between CBP and p300. -

Immunofluorescent analysis of MCF-7 cells, labeling CREBBP with ab2832 (right) compared with a negative control without ab2832 (left). Cells were formalin fixed, permeabilized with 0.1% Triton X-100 for 5-10 minutes, and blocked with 3% BSA-PBS for 30 minutes at room temperature. Cells were incubated with anti-KAT3A/CBP diluted 1/100 in 3% BSA/PBS overnight at 4°C. Actin was stained using Alexa Fluor 554 (red) and nuclei were stained with DAPI (blue). The nuclear localization of KAT3A/CBP can be observed (green).

IHC image of CREBBP staining in human pancreas formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab2832, 5µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.
For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times. -
