Before revision:  We apply the theory to calculate binding affinities between various pairs of IDP sequences, and extract a parameter jSCDencompassing the sequence-specific IDP-IDP interaction. Our theory provides a general framework to investigate IDP-IDP interaction .
After revision:  We apply the theory to calculate binding affinities between various pairs of IDP sequences, and extract a parameter jSCDencompassing the sequence-specific IDP-IDP polyelectrostatic interactions .
