  • Patent number: 5980892
    Abstract: The present invention relates to monoclonal antibodies which recognize defined regions of the T-cell receptor (TCR). In a specific embodiment, the invention provides monoclonal antibodies which are reactive with a constant region of the alpha chain of the TCR. In particular embodiments, the invention relates to two monoclonal antibodies, termed .alpha.F1 and .alpha.F2, which react with two different epitopes on the framework region of the .alpha. monomer of the TCR molecule. In another specific embodiment, the invention is directed to monoclonal antibodies reactive with a variable region of the beta chain of the TCR. In particular, the invention provides two monoclonal antibodies, termed W112 and 2D1, which react with .beta. chain variable regions V.beta.5.3 and V.beta.8.1, respectively. In another specific embodiment, the invention is directed to monoclonal antibodies reactive with a variable region of the delta chain of the TCR. In particular, the invention provides monoclonal antibody .delta.

  • Patent number: 5766947
    Abstract: The invention is directed to monoclonal antibodies reactive with a member of the V.beta.3 family variable region of the beta chain of the TCR. More particularly, the invention provides for detection of the V.beta.3.1 subfamily. In a specific embodiment the invention provides for detection of V.beta.3.1, without cross-reacting with other V.beta.3 family variable regions. In a specific embodiment, the monoclonal antibodies of the invention do not react with V.beta.3.2. In particular, the invention provides monoclonal antibodies, termed 5E4 and 8F10, which react with the variable region of a member of the V.beta.3 family. In various embodiments of the invention, these antibodies, or fragments or derivatives thereof, can be used to bind with a member of the V.beta.3 family TCR variable region amino acid sequences, either as part of an intact TCR or peptide, or T cell-surface molecule, or a fragment thereof.
