Genetic polymorphism of mouse immunoglobulin light chains revealed by isoelectric focusing
D Gibson
Light chains isolated from normal immunoglobulin of unimmunized mice were
analyzed by gel isoelectric focusing. Examination of the focusing patterns
of light chains from nine inbred mouse strains showed that six of the
strains (SWR/J, C3H/HeJ, DBA/1J, A/J, CBA/J, and C57BL/6J) possessed a
virtually identical spectrum of focusing bands, while the remaining three
strains (RF/J, AKR/J, and C58/J) showed clear differences involving several
bands. Analysis of the light chains of individual SWR/J, C58/J, and F1
hybrid mice indicated that the differences in focusing pattern were
inherited in a simple codominant fashion. A new procedure was developed for
the rapid analysis of light chains from small quantities of serum.
