Molecular weight was the strongest retention-promoting factor, which can be at least partly explained by the relation between their residue counts and molecular weights. A linear regression of molecular weight against the number of acidic, basic, and hydrophilic groups showed an R 2 of 0.64, with slope highly significant at the 99.9% level.
