The products of kappa immunoglobulin gene recombination have been characterized in two murine plasmacytomas to examine the relationship between V-J products and reciprocal elements. By cloning, sequencing, hybridization, and application of the polymerase chain reaction, we have established the direct relationship of the kappa recombination products in these cells. The results provide stronger support for the intrastrand mechanism of kappa gene recombination as well as demonstrating a role for secondary, corrective recombinations.
