Abstract

A porcine cDNA library was constructed using poly(A)+ RNA isolated from the spleen of an adult Minnesota miniature swine. Screening the library with antisera specific for porcine immunoglobulin light chains resulted in the selection and isolation of two recombinant clones, PLC18 and PLC3, which encode for kappa and lambda light chains, respectively. These cDNAs contain sequence information for a portion of the variable region and all of the constant region. The lengths of the constant regions are 105 amino acids for lambda and 108 amino acids for kappa. The deduced amino acid sequences of porcine immunoglobulin light chains share a high degree of homology with similar sequences from other species in both the fourth framework region and the constant region.
