Human chorionic gonadotropin · Chorionic gonadotropin
| Classification | Heterodimeric glycoprotein hormone (α and β subunits) |
|---|---|
| Molecular weight | ~36.7 kDa (glycosylated) |
| CAS number | 9002-61-3 |
| Solubility | Reconstitute gently with bacteriostatic water; swirl rather than shake. Glycoproteins denature under mechanical agitation. |
| Reported half-life | Notably long for a glycoprotein hormone, attributed to extensive glycosylation and a sialic-acid-rich β-subunit C-terminal peptide. |
International orders have a 3-vial minimum per product. Case pricing shown is international; US warehouse case pricing may differ and is shown at checkout.
A heterodimeric glycoprotein consisting of a 92-residue α subunit — shared with LH, FSH, and TSH — and a distinct 145-residue β subunit that confers receptor specificity. Note that potency is expressed in international units rather than mass, because glycosylation heterogeneity makes mass an unreliable measure of activity.
The following describes contexts in which this compound appears in published laboratory literature. Nothing here is a claim of efficacy, safety, or suitability for any use in humans or animals.
| Lyophilized powder | Store lyophilized powder at -20 °C, protected from light. |
|---|---|
| After reconstitution | Store at 2–8 °C and use within approximately 4 weeks. Glycoproteins are sensitive to mechanical agitation — swirl, never shake. |
| Shipping | Ships at ambient temperature. |
