Abstract
The production of a monoclonal antibody specific for sheep kappa light chain protein is described. The monoclonal antibody was designated McM11 and its specificity was verified using western blots of sheep IgG and slides of efferent lymph cells. The specificity of McM11 was confirmed by specific recognition of fusion proteins expressed by recombinant phage containing sheep kappa cDNAs. N terminal sequence of the light chain recognized by McM11 showed homology to kappa type light chains. McM11, together with McM6, a lambda specific monoclonal antibody, was shown by two color FACS analysis of sheep blood lymphocytes to recognize all sheep light chains.
