Lab designation: RA3 6B2; A rat-mouse hybridoma cell line producing a monoclonal IgG2a rat AB which recognizes a B cell specific form of the T200 family of cell surface glycoproteins. B220 was first characterized by another MAB, RA3-3A1.
The 4G7 hybridoma secretes an IgG1 antibody that is specific for normal and malignant B lymphocytes and can be used for the study of B cell differentiation and for the characterization of lymphoid malignancies.
Alloreaction-associated antigen (ARAg) is a novel member of the immunoglobulin superfamily. This invention's issued US patent claims composition of matter of ARAg polypeptides and nucleic acids encoding ARAg polypeptides.
