In order to examine the diversity of antibody light chains, we have developed an analytic isoelectric focusing procedure which permits the routine analysis of L chains from antibodies raised in individual mice. We have used this technique to demonstrate that the light chains of IgM and IgG anti-group A streptococcal antibodies raised in SWR mice are probably shared. Interestingly, numerous light chain spectrotypes are shared between individual mice whose 7S antibody focusing patterns differ.
