Product Overview
This rabbit polyclonal antibody detects carbonyl reductase (gene CBR1) in human, mouse and rat samples and is validated for Western blot, IHC, ICC/IF, flow cytometry and ELISA. The predicted molecular weight is 30.4 kDa, and the supplier reports an observed band at about 36 kDa.
Carbonyl reductase 1 (CBR1) is an NADPH-dependent cytosolic enzyme of the short-chain dehydrogenase/reductase family. It reduces a wide range of carbonyl compounds, including prostaglandins, quinones and xenobiotics, and converts the anthracyclines doxorubicin and daunorubicin into cardiotoxic alcohol metabolites. It is studied in drug metabolism and anthracycline cardiotoxicity.
