Chorionic Gonadotropin (hCG) Fragments are proteolytic derivatives of human chorionic gonadotropin, utilized primarily in pharmaceutical research and diagnostic assay development. These fragments retain specific immunogenic epitopes while lacking full biological activity, produced via controlled enzymatic digestion or chemical cleavage. Unlike the intact glycoprotein hormone, these fragments exhibit reduced molecular complexity, facilitating their use as calibration standards.
Strictly designated for in vitro diagnostic or research use only; not approved for therapeutic administration. Storage requires refrigeration at 2-8°C to maintain stability. Handling mandates personal protective equipment due to potential allergenicity and biohazard risks associated with recombinant or plasma-derived proteins.
