Biochemical characteristics of the major linear B cell epitope 169–190aa of the Ro60 kDa autoantigen. Important amino acid residues connote the amino acids contributing to the antigenicity of the molecule [5]. Minimum length denotes the minimum required length of the epitope, which retains the antigenicity of the molecule [5]. Finally phosphorylated and citrullinated amino acids reveal those residues that were modified for this study.
