Received July 14, 1978. Nucleotide sequence analysis and restriction endonuclease mapping have been used to characterize a cDNA copy of immunoglobulin MOPC 21 Kappa mRNA cloned in the bacterial plasmid pMB9. Three regions of the inserted cDNA of plasmid pL211 have been sequenced and match the known protein sequence at amino acid residues 124, 128138 and 171179. With these sequences to provide absolute correlations between the restriction map and the structural gene sequence it has been possible to exactly deduce the positions of all 11 of the insert restriction sites mapped within the structural gene. The pL211 insert contains the complete variable and constant regions as well as parts of the 3' untranslated and polypeptide leader coding sequences.
