Storage & handling
- Storage (Lyophilized): Store at -20°C in original sealed vial. Protect from light and moisture.
- Storage (Reconstituted): Store at 2-8°C for up to 7 days. For extended storage, prepare aliquots and store at -20°C or -80°C. Avoid repeated freeze-thaw cycles.
- Reconstitution: Reconstitute with sterile water, bacteriostatic water, or sterile PBS. Use aseptic technique. Allow to dissolve completely before use.
- Stability: Lyophilized product stable for 36 months when stored at -20°C as directed.
- Handling: Wear appropriate personal protective equipment. Handle according to institutional biosafety protocols for biological materials.
Research notes
Protein Structure: hCG is a heterodimeric glycoprotein hormone consisting of an α-subunit (shared with FSH, LH, and TSH) and a unique β-subunit.
Reconstitution Recommendations: For optimal stability, reconstitute at a concentration of 100-500 IU/mL. Higher concentrations may require the addition of carrier protein (e.g., 0.1% BSA) to prevent surface adsorption.
Activity Measurement: Biological activity is determined by in vitro bioassay and calibrated against WHO International Standard.
Classification: Analytical Standard / Research Use Only (RUO) biological material.
Regulatory Status: This material is not intended for diagnostic, drug, household, agricultural, cosmetic, or veterinary applications. Purchaser assumes full responsibility for compliance with all applicable federal, state, and local regulations governing the use and handling of biological research materials.
