背景介绍 PMSA (prostate-specific membrane antigen), also known as Folate hydrolase 1 (FOLH1), is expressed at high levels on prostate cancer cells. It has been reported to play a role in tumor progression through the PI3K-Akt and MAPK-ERK1/2 pathways. PMSA/FOLH1 has been used as a target for imaging prostate cancer and is expressed in other tumor types and some normal tissues. Currently, PMSA/FOLH1 is the target of clinical trials of CAR-T cells and bi-specific antibodies. 产品介绍 Recombinant clonal stable CHO cell line constitutively expressing full length human PMSA protein (Genbank #NM_004476.1). Surface expression of PMSA was confirmed by flow cytometry. Each stable clonal cell line was selected for different levels of PMSA expression to mimic different stages of cancer target cells with various PMSA expression levels.
