Light chain heterogeneity in the amphibian Xenopus.

Hsu E, Lefkovits I, Flajnik M, Du Pasquier L.


???displayArticle.abstract???
Three subpopulations of light chains in Xenopus can be distinguished by monoclonal antibodies as well as by electrophoretic mobility on SDS-PAGE, peptide map and cell surface distribution. Analysis of these proteins from LPS-stimulated lymphocytes culture supernatants by two-dimensional gel electrophoresis showed a heterogeneity comparable to that observed for mouse kappa light chains. However, evidence from the selective expression of light chain subpopulations, as well as highly restricted light chain representation in anti-DNP antibodies, supports earlier findings that an antibody response in Xenopus is greatly limited in heterogeneity.
