Assays and methods
HPLC Purity
Reverse-phase HPLC quantifies peptide purity to 0.01% with UV detection across configurable gradients.
Detection: 214 nm · LOQ: 0.05%
LC-MS Identity
Liquid chromatography paired with mass spectrometry to confirm molecular weight against the expected target.
Mass accuracy: ±0.1 Da
Concentration
Quantitative concentration verification using calibrated reference standards. Reported in mg/vial.
Range: 0.1–50 mg · CV < 2%
Identity Confirmation
Cross-method confirmation combining retention time matching with mass spectral fingerprinting.
Dual-method confirmation
Endotoxin / Sterility
Optional endotoxin screening (LAL) and sterility verification for injectable-grade product workflows.
USP <85> aligned
Custom Assays
Bespoke methods for novel peptides, conjugates, and complex matrices. Method development included.
Method dev: 2–3 weeks
