HCG-beta is secreted in large quantities by the placenta and normally is found in maternal circulation during early fetal development. Polyclonal Rabbit Anti-Human Chorionic Gonadotropin is intended for use in immunocytochemistry. The antibody labels hCG-containing cells and may be used for the demonstration of trophoblastic elements, e.g. in germ cell tumors.
