HCG 5000IU

Product overview

HCG 5000IU is a human chorionic gonadotrophin research-material listing with a supplier-labelled activity of 5000 international units per vial (SKU HC5K). International units describe biological activity; they are not a direct statement of mass or percentage purity.

hCG is a glycoprotein hormone studied through its interaction with the luteinising hormone/chorionic gonadotrophin receptor, commonly shortened to LH/CG receptor. Laboratory work examines receptor signals and methods for measuring hCG.

What researchers study

• LH/CG receptor activation and signals produced inside cells
• Comparisons between LH and hCG in controlled receptor models
• Biological-activity measurements and immunoassay responses
• Identity, formulation and potency assessment against suitable reference standards

Evidence and limitations

Receptor studies and measurements using established reference preparations do not verify the activity of this vial. Biological activity and immunoassay response are different measurements; one result does not automatically establish the other.

The stated 5000 IU remains a supplier label declaration until supported by an applicable potency assay and reference-standard traceability. The source material, formulation and excipients also require batch documentation. This product is not supplied as a WHO international reference standard or an authorised medicinal formulation.

Storage and laboratory handling

As supplied: Keep the original container closed and follow the batch label, safety data and supplier documentation. Specific temperature requirements and usable life have not yet been verified for this presentation. Storage conditions for licensed medicines or international standards must not be transferred to this material without supporting evidence.

After laboratory preparation: Validate compatibility, activity and usable life for the chosen method. No universal preparation method or post-preparation shelf life is stated.

Handle only in an appropriately equipped laboratory using suitable personal protective equipment and local disposal procedures.
