Hormones Peptide Testing
Glycoprotein hormones (HCG, HMG) require bioassay or LC-MS of tryptic fragments; small-molecule hormones (enclomiphene) need HPLC-UV plus chiral analysis to separate the active trans-isomer from clomiphene.
Recommended Panel
- ✓Chiral HPLC (enclomiphene)
- ✓LC-MS
- ✓Potency by ELISA where appropriate
Common Impurities to Watch For
Cis/trans-isomer contamination, glycoform heterogeneity, degraded HCG.
