Product Overview
This rabbit polyclonal antibody recognizes glycoprotein hormones alpha chain (gene CGA) in human, mouse and rat samples and is validated for Western blot, IHC and flow cytometry.
The glycoprotein hormone alpha subunit (CGA) is the common alpha chain shared by TSH, LH, FSH and hCG. Each hormone combines this alpha chain with its own beta chain, which gives receptor specificity, so CGA is studied in pituitary and placental endocrinology.
