Description
Glutamate carboxypeptidase 2 (FOLH1/PSMA) cleaves the terminal glutamate from folylpolyglutamates and serves as a validated target in prostate cancer and neurological disorders, making quantitative binding studies critical for therapeutic antibody development. This mammalian-expressed protein spanning residues 44–750 demonstrates robust antibody recognition in functional ELISA, with EC50 values of 11.74–15.02 ng/mL and 3.853–4.303 ng/mL for two distinct anti-FOLH1 antibodies, providing quantitative benchmarks for epitope mapping studies and inhibitor screening assays where competitive binding must be measured. The N-terminal 10xHis tag facilitates purification while preserving the catalytic domain architecture required for IC50 determination and inhibition mechanism studies. With purity exceeding 90% by SDS-PAGE and endotoxin levels below 1.0 EU/μg, this preparation meets the quality thresholds commonly required for kinetic parameter analysis and serves as a positive control in enzyme-linked assays evaluating drug candidates targeting the FOLH1 active site.
