Molar extinction coefficient (280 nm)
ext_coeff_280 · M^-1 cm^-1
ε280 (reduced) = 5500·nTrp + 1490·nTyr. Cystine-bonded form (+125 per disulfide) and A280(0.1%, 1 g/L) carried in payload. Exact match vs BioPython.
Calculated from the parent-residue sequence when a standard sequence is available. Values appear on peptide records under the physicochemical profile.
