Product Overview
This rabbit polyclonal antibody recognizes bifunctional 3'-phosphoadenosine 5'-phosphosulfate synthase 2 (gene PAPSS2) in human, mouse and rat samples and is validated for Western blot, IHC, ICC/IF, flow cytometry and ELISA. The predicted molecular weight is 69.5 kDa, and the supplier reports an observed band at about 70 kDa.
PAPSS2 is one of two bifunctional enzymes that make PAPS, the activated sulfate donor for all sulfation reactions. It is important for sulfation of cartilage proteoglycans and steroids such as DHEA, and loss of PAPSS2 affects skeletal growth.
