Immunohistochemistry analysis of hCG was performed on human placenta tissue and is showing positive staining in extra cellular spaces. To expose target proteins, antigen retrieval was performed by microwaving tissues for 20 minutes in 10mM sodium citrate buffer (pH 6.0). Tissue slides were probed with hCG monoclonal antibody (Product # MIH9812) at a dilution of 1:20, overnight at 4C in a humidified chamber without (left panel) or with hCG antibody control (right panel). Tissues were washed, and incubated with secondary antibody (conjugated with HRP) for 30 min at room temperature in a humidified chamber. Detection was performed using DAB substrate kit. Tissues were counterstained with hematoxylin and dehydrated to prep for mounting. Images were taken at 20x magnification.

The observed molecular weight of alpha-hCG and beta-hCG are approximately 20-22 kD & 27-32 kD respectively.
The molecular weight is higher than the predicted molecular weight due to post translational modification.
MIH9812 was formerly sold as a Seradyn product.
The four human glycoprotein hormones chorionic gonadotropin (CG), luteinizing hormone (LH), follicle stimulating hormone (FSH), and thyroid stimulating hormone (TSH) are dimers consisting of alpha and beta subunits that are associated noncovalently. The alpha subunits of these hormones are identical, however, their beta chains are unique and confer biological specificity. The protein encoded by this gene is the alpha subunit and belongs to the glycoprotein hormones alpha chain family.
