The antibody was purified by affinity chromatography, and conjugated with PE under optimal conditions. The solution is free of unconjugated PE and unconjugated antibody.
PSMA (prostate-specific membrane antigen) is a type II transmembrane zinc metallopeptidase, belonging to the M28 peptidase family. It possesses hydrolyzing enzyme activities and is also known as FOLH1 (folate hydrolase 1), GCP2 (glutamate carboxypeptidase II), and NAALADase I (N-acetylated-alpha-linked acidic dipeptidase I). PSMA is expressed by normal and malignant prostate epithelial cells, by urothelial adenocarcinoma, and vasculatures of other malignancies. It is also found in the nervous system.
