RT Journal Article SR Electronic T1 Characterization of a monoclonal antibody which detects all murine alpha beta T cell receptors. JF The Journal of Immunology JO J. Immunol. FD American Association of Immunologists SP 2736 OP 2742 VO 142 IS 8 A1 Kubo, R T A1 Born, W A1 Kappler, J W A1 Marrack, P A1 Pigeon, M YR 1989 UL http://www.jimmunol.org/content/142/8/2736.abstract AB Research on the specificities, functions, and maturation of T cells would be greatly aided by a collection of monoclonal antibodies which distinguishes different types of TCR. With this end in mind hamsters were immunized and tested for production of pan-reactive anti-mouse alpha beta TCR antibodies. In this report we describe the properties and uses of a mAb, H57-597, produced from one of these animals. The mAb reacts with surface receptors on all alpha beta TCR-bearing cells and does not react with receptors on gamma delta+ T cells. In an immobilized form, this antibody can directly activate T cells bearing alpha beta TCR. It can be used in immunoprecipitation reactions to precipitate receptor from the appropriate cell types. In combination with anti-CD3, the antibody can be used in cytofluorographic analyses to measure numbers of CD3+, alpha beta+, and CD3+, gamma delta+ cells in the thymus and periphery.
