Amino acid sequence of the human myeloma lambda chain Win

The complete amino acid sequence of the variable region of a human myeloma immunoglobulin light chain (Win) has been determined. The sequence of the constant region has been verified by compositional analysis of its tryptic peptides. The amino acid sequence of the light chain Win corresponds to sub group II and shows no unusual amino acid replacements in its constant or variable regions when compared to other human gamma chains.
