Typical analytical method

HPLC columnC18 reversed-phase (300 A pore, C4/C8 suitable for large/lipidated)
Mobile phaseA: water + 0.1% TFA; B: acetonitrile + 0.1% TFA; linear gradient (e.g. 5-65% B over 20-30 min)
Detection214-220 nm (peptide bond) and 280 nm (Trp/Tyr present)

General literature method. The lot CoA records the method actually used. How to read an HPLC chromatogram.
