Immune & Anti-Inflammatory Peptide Testing
Immunomodulators are particularly sensitive to oxidation and endotoxin contamination — both of which directly impact biological activity. Mandatory LAL screening for every injectable lot.
Recommended Panel
- ✓RP-HPLC purity
- ✓ESI-MS identity
- ✓Endotoxin (LAL)
- ✓SEC for LL-37 aggregation
Common Impurities to Watch For
Methionine/Trp oxidation, deamidation, endotoxin, aggregation in LL-37.
