Four of five RAG-expressing JCkappa-/- small pre-BII cells have no L chain gene rearrangements: detection by high-efficiency single cell PCR.

Single cell PCR assays have been further developed that detect over 80% of all VkappaJkappa, VkappaRS, and VlambdaJlambda rearrangements at efficiencies between 70% and 90%. These IgL chain gene rearrangement assays were used with small pre-BII cells that develop in comparably high numbers in the bone marrow of wild-type, Ckappa-deficient, and JCkappa-deficient homozygous and heterozygous mice. In all of these mice, only 15%-25% of all small pre-BII cells carry VlambdaJlambda rearrangements. These results confirm that lambdaL chain gene rearrangements occur independently of kappaL chain gene rearrangement and expression. They also show that a large part of the small pre-BII cells that express the rearrangement machinery can develop without IgL chain gene rearrangements.[1]
