Abstract
One-dimensional isoelectric focusing followed by immunoblotting and development of the immunoblots with the monoclonal antibody HC-10, raised against denatured HLA class I heavy chains, was used to demonstrate biochemical variation in cattle MHC (BoLA) class I molecules. The bands obtained correlated well with BoLA-A specificities. Two or three bands were identified for the specificities w7, w8, w16, w18, w21, cph43 and cph49, whereas no bands were observed for the specificity w2. Two serologically indistinguishable subtypes of specificity w18 were identified.
