General notes
For the WB, please note the subcellular localization and distribution of the BCRP/ABCG2 in Normal Human Tissues: PMID:11309308
We have received mixed feedback from customers, the antibody showed 45-50 kDa band size in A549 and Caco2 cell lines against predicted size of 72kDa. In response to data we have received we no longer guarantee this antibody for western blot. ABCG2 is a multi-pass membrane protein so for troubleshooting we would recommend heating the samples at 60-70C for 15-20 minutes instead of boiling and as this protein exists as homodimer so complete reduction of samples is highly recommended. In case of any other question please email scientific support team.
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
Breast Cancer Resistance Protein (BCRP) is a 70 kDa ATP-Binding Cassette membrane transport protein involved in multidrug resistance. BCRP may be over-expressed in cancer cell lines selected with doxorubicin / verapamil, topotecan or mitoxantrone. -

Function
Xenobiotic transporter that may play an important role in the exclusion of xenobiotics from the brain. May be involved in brain-to-blood efflux. Appears to play a major role in the multidrug resistance phenotype of several cancer cell lines. When overexpressed, the transfected cells become resistant to mitoxantrone, daunorubicin and doxorubicin, display diminished intracellular accumulation of daunorubicin, and manifest an ATP-dependent increase in the efflux of rhodamine 123. -
Tissue specificity
Highly expressed in placenta. Low expression in small intestine, liver and colon. -
Sequence similarities
