hCG

Alternative Names: CG, hCG, Chorionic gonadotropin

Human chorionic gonadotropin (hCG) is a peptide hormone synthesized during pregnancy. It is initially produced by the embryo shortly after conception and later by the syncytiotrophoblast, a component of the placenta. Its main function is to preserve the corpus luteum of the ovary and ensure the continued production of progesterone, which is essential for maintaining pregnancy in humans. hCG may also have other roles, such as influencing the immune tolerance of the pregnancy. Typically, early pregnancy testing relies on the identification or quantification of hCG.

Product Description

Human Chorionic Gonadotropin (hCG) is a hormone primarily produced during pregnancy by the placenta. Belonging to the glycoprotein hormone family, hCG plays a crucial role in maintaining the corpus luteum, which produces progesterone to support the early stages of pregnancy. With a molecular weight of approximately 36.7 kilodaltons, hCG is composed of two subunits, alpha and beta, that are responsible for its biological activity. This hormone is commonly used as a marker in pregnancy tests and can also be administered therapeutically to stimulate ovulation in women undergoing fertility treatments.

Product Guarantee

If your product is within its expiration period, and has not performed according to expectations, fill out the sample return form. Return the unused sample frozen, with the auto generated packing slip to the address on the instructions. You will receive a full refund along with a replacement of the unused portion (inclusive of the failed test). Damages do not cover any additional costs incurred for failed experimentation. 

Storage Instruction

Lyophilized hCG although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution CG-beta should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.

Sample Prep Instruction

It is recommended to reconstitute the lyophilized Human Chorionic Gonadotropin in sterile 18MΩ-cm H2O not less than 100 µg/ml, which can then be further diluted to other aqueous solutions.
