Human Pregnancy Specific Beta-1-Glycoprotein 2 (PSG2) ELISA Kit

The Assay Genie immunoassay kit quantifies Pregnancy Specific Beta-1-Glycoprotein 2 (PSG2) in human research specimens. PSG2 belongs to a family of glycoproteins synthesized by placental syncytiotrophoblast cells, where members contribute to immune modulation at the maternal-fetal interface throughout gestation. Researchers studying reproductive biology, placental development, or pregnancy complications including preeclampsia and intrauterine growth restriction employ this kit to monitor PSG2 concentrations across gestational stages or compare normal versus pathological placental expression.

The workflow follows an immunometric procedure: pre-coated microwell strips receive prepared standards and samples, then biotinylated detection antibody, streptavidin-HRP conjugate, and chromogenic substrate in sequence. Optical density is read on a microplate reader, with concentrations derived from the standard curve. Each Assay Genie kit ships with a pre-coated plate formatted for 96 individual determinations, lyophilized reference standards, detection antibody, enzyme conjugate, wash buffer, substrate, and stop solution.

Acceptable specimen types cover serum samples, plasma samples, and tissue homogenate preparations, supporting work with archived clinical collections, in vitro placental explant cultures, or experimental animal-model tissue samples. The kit is configured for research use only.
