Indian major carps (IMC), rohu (Labeo rohita), catla (Catla catla) and mrigal (Cirrhinus mrigala) were immunized with bovine serum albumin and the serum immunoglobulin M (IgM) was purified by affinity chromatography. The heavy and light chain of IgM of all the three species of IMC were about 88 and 26 kDa, respectively. Anti-fish lgM antibody against all the three species were raised in mice and the reaction of anti-fish IgM antibodies with IgM of all the three species of IMC were studied by Western blot. The anti-fish IgM antibodies reacted strongly with the heavy chain of the same species against which it was raised while the reactions with the heavy chain of other species were milder indicating some degree of epitope sharing among the heavy chains of IgM of IMCs. However, there was no cross-reaction with the light chain of any of the IgM. (C) 2008 Elsevier Ltd. All rights reserved.
