HCG (Human Chorionic Gonadotropin) 5000 IU

HCG 5000 IU — a cornerstone gonadotropin for endocrine research
Human Chorionic Gonadotropin is one of the most thoroughly characterised glycoprotein hormones in endocrinology. This 5000 IU vial supplies it as sealed, batch-tested lyophilised material for reproductive and hormone-signalling research.

What is HCG?

HCG is a glycoprotein hormone composed of two subunits: an alpha chain shared with LH, FSH and TSH, and a beta chain unique to HCG that determines its receptor specificity. Because it binds the LH/HCG receptor, it functions in research as a potent and long-acting surrogate for luteinising hormone — a property that has made it a standard probe compound in gonadal steroidogenesis studies. Its measurement in IU rather than milligrams reflects its characterisation by biological activity rather than mass alone.

Research interest

• LH/HCG receptor signalling — used by researchers examining gonadal cell responsiveness and receptor kinetics.
• Steroidogenesis pathways — investigated in research contexts concerned with how gonadotropin signalling drives steroid hormone synthesis.
• Reproductive endocrinology — a long-standing reference compound in studies of the hypothalamic-pituitary-gonadal axis.
• Glycoprotein hormone structure — cited in literature exploring how subunit glycosylation governs half-life and receptor affinity.
• Assay calibration — its IU-based standardisation makes it useful as a benchmark in comparative bioactivity work.

As a glycoprotein rather than a simple linear peptide, HCG is more structurally complex and correspondingly more sensitive to handling. Proper cold storage and gentle reconstitution are essential to preserving its tertiary structure and therefore its receptor-binding behaviour in assay conditions.

Handling & storage

Store sealed lyophilised vials at -20 °C for long-term stability; short periods at 2-8 °C are generally tolerated during transit and handling. Keep vials sealed, protected from light and away from moisture and repeated temperature swings. Glycoprotein hormones tolerate agitation poorly; any laboratory reconstitution should be performed by directing diluent gently down the vial wall rather than onto the lyophilisate, and the vial should be swirled rather than shaken. Keep solutions refrigerated and avoid repeated freeze-thaw, which promotes aggregation and loss of activity.
