Computed physicochemical parameters of candidate CPP sequences

Name Sequence Hydrophobicity Hydropathicity Amphipathicity Hydrophilicity Charge
Ku70 VPMLK 0,03 0,88 0,73 −0,32 1
FGF PIEVCMYREP −0,15 −0,29 0,50 0,11 −1
Pen RQIKIWFQNRRMKWKK −0,54 −1,73 1,53 0,46 7

The selected sequences show marked differences in parameters relevant to cell penetration. This broad range of values is indicative of the diversity of selection from the wide field of known CPPs.
