Abstract

We developed a panel of monoclonal antibodies (MAb) against chicken β2-microglobulin (chβ2M) by fusions between SP2/0 myeloma cells and spleen cells from mice immunized with a synthesized peptide corresponding to positions 91-119 of the COOH domain of chβ2M. Two of them, 6E7 and 3D1, identified as IgG1/κ, could react with chβ2M protein from avian macrophage HD11 cells and human 293T cells transfected with pcDNA3.1-chβ2M in immunofluorescence assays. Only a 12 kDa protein band of chβ2M could be detected in the HD11 and 293T/chβ2M cell lysates by Western blot analysis. Chicken β2M in serum and plasma could be found in Western blot by MAb 3D1. Moreover, MAb 3D1 also recognized the chβ2M antigen on the cell membranes in flow cytometry. Immunohistochemical staining with these MAbs revealed that chβ2M was present in chicken thymus, spleen, and bursa. These MAbs will be good tools for analyzing the mechanism of the chicken immune system.
