Anti-CSH1 Antibody

This rabbit polyclonal reagent from Antibodies.com detects human chorionic somatomammotropin hormone 1 (CSH1), supplied as 100 µl of unconjugated antiserum for Western blot and immunohistochemistry work. CSH1, also called placental lactogen, is secreted by syncytiotrophoblast cells of the placenta and contributes to maternal metabolic adaptation and fetal growth during pregnancy.

Validated applications include Western blot on cell or tissue lysates for protein-level detection, and IHC on formalin-fixed paraffin-embedded sections for spatial localization studies. Aliquot upon first thaw and store at -20°C to limit freeze-thaw cycles; the working stock can be kept at refrigerated temperature for short-term use. The polyclonal host response recognizes multiple epitopes on CSH1, which is helpful when probing denatured targets on membranes or partially masked antigens in archived placental specimens.

Researchers in reproductive biology, placental pathology, and gestational endocrinology use this primary antibody to confirm CSH1 expression in trophoblast-derived cells, compare placental hormone profiles across gestation, and investigate links between placental lactogen signaling and conditions such as preeclampsia or intrauterine growth restriction. It can be paired with related markers in the somatotropin and prolactin family to build a fuller picture of placental hormone biology in human pregnancy research.
