Anti-PSG1 Antibody

This rabbit polyclonal antibody from Antibodies.com targets the human pregnancy-specific beta-1-glycoprotein 1 (PSG1), a secreted immunoglobulin-superfamily protein produced by placental syncytiotrophoblasts during gestation. Raised in rabbit and supplied as 100 µL of unconjugated antiserum, the reagent is validated for Western blot and ELISA workflows against human samples.

PSG1 belongs to a multigene family of pregnancy-specific glycoproteins investigated as serum biomarkers in reproductive biology and as aberrantly expressed antigens in several epithelial tumors, making this antibody useful for placental development studies, maternal-fetal interface profiling, and tumor expression surveys. The polyclonal format allows recognition of multiple epitopes across the PSG1 molecule, supporting detection in cell lysate and tissue-derived preparations when paired with standard HRP- or fluorophore-conjugated secondary reagents.

The unconjugated presentation lets researchers configure their own detection chemistry, including chromogenic, chemiluminescent, or immunofluorescence readouts depending on the chosen secondary antibody. Each vial is intended for research use only and should be handled under short-term storage conditions appropriate for an unconjugated polyclonal antiserum.
