Name: Placental Lactogen (hPL) Polyclonal Antibody
Description and applications: Human placental lactogen (hPL) is known to originate in the syncytiotrophoblasts. Ultrastructural localization indicates that placental lactogen is stored in small morphologically distinctcytoplasmic granules within these cells and has adifferent secretory mechanism from other hormonal peptides such as human chorionic gonadotropin.
The level of expression of placental lactogen through pregnancy increases gradually to term. Immunostaining for hPL is useful for the differential diagnosis of choriocarcinoma where it is expressed in most cases, placental site trophoblastic tumour and the trophoblastic pseudotumoral lesions such as placental site nodule and exaggerated placental site reaction.
Composition: anti-human Placental Lactogen rabbit polyclonal antibody purified from rabbit anti-serum. Prepared in 10mM PBS, pH 7.4, with 0.2% BSA and 0.09% sodium azide
Immunogen: Purified human placental lactogen
