Extinction Coefficient:Extinction coefficients are in units of M-1 cm-1, at 280 nm measured in water.

Ext. coefficient    6990
Absorption 0.1% (=1 g/l)    7.524
Aromaticity:0.286

Aromaticity is the calculated relative frequency of Phe+Trp+Tyr
Instability Index:The computed Instability Index (II) is : 31.97

This indicates that the protein/peptide is stable
