SUMMARY, EXPLANATION AND LIMITATIONS:
Human placental lactogen (HPL) is produced in syncytiotrophoblast. The ultrastructural localization shows that placental lactogen is stored in smoll cytoplasmic granules, which are morphologically distinct between them and has a different secretor mechanism to others hormone peptides like human chorionic gonadotrophin (HCG). The HPL expression during pregnancy increases gradually until the end of it.
Immunogen: Purified human placental lactogen.
Staining pattern: Cytoplasmic.
Positive control: Tissue sample from placenta.
This antibody is designed for the specific localization of HPL using IHC techniques in formalin-fixed, paraffin-embedded tissue sections.
