Triclonal gammopathy

This figure illustrates the immunofixation pattern of a single serum specimen with antisera to heavy chain determinants of IgA, IgG, and IgM, and to kappa and lambda light chain determinants. It shows a discrete IgG band and a discrete kappa band with similar mobility, indicative of an IgG kappa monoclonal protein. There are also IgA lambda and IgM kappa monoclonal proteins.
