Anti-PSG1 Antibody

Raised in rabbit and supplied as an unconjugated polyclonal antiserum, this primary antibody from Antibodies.com targets PSG1 (pregnancy-specific beta-1-glycoprotein 1), a member of the CEA family expressed in placental trophoblast. The reagent is offered in two pack sizes — 50 µl at $415 and 100 µl at $595 — and is validated for Western Blotting (WB) and Immunofluorescence (IF) on human samples. As a polyclonal preparation, the antibody recognizes multiple epitopes across the PSG1 protein, which helps to maximise sensitivity when detecting low-abundance endogenous targets. The host species is rabbit (isotype IgG), the clonality is polyclonal, and the conjugate is unconjugated, allowing the end user to pair it with their preferred reporter-labelled secondary antibody for fluorescence, chromogenic or HRP-based detection. The product is dispatched from St. Louis, MO and is shipped refrigerated on wet ice; upon arrival it should be aliquoted and stored at -20 °C to preserve activity, avoiding repeated freeze/thaw cycles. For research use only, this anti-PSG1 polyclonal fits neatly into workflows involving placental tissue or trophoblast-derived cell lines, where PSG1 expression can be tracked by WB band intensity or by IF signal localisation. The 50 µl format is suitable for laboratories running a limited panel of blots and imaging experiments, while the larger 100 µl option offers better value for higher-throughput studies.
