Abstract
Abstract Disclosed is a heterodimeric T lymphocyte receptor subunit. The subunit consists of a signal peptide, variable, joining, constant, transmembrane, and cytoplasmic regions. The structure, amino acid, and nucleotide sequence of the lymphocyte receptor subunit were determined using cDNA clones derived from a functional murine cytotoxic T lymphocyte clone. The genes corresponding to these cDNA are expressed and rearranged specifically in T cells and have significant sequence homologies to immunoglobulin V and C genes. T cell receptor subunits may be produced from the cDNA clones. The protein molecules may be further used for the production of T-cell clone specific antibodies.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
76 words
A method for making an isolated antibody specific for the variable region of the alpha subunit of a mammalian T lymphocyte receptor, wherein the antibody is produced by the method comprising: expressing the variable region of the alpha subunit of the T lymphocyte receptor in a genetically engineered host selected from the group consisting of procaryotic and eucaryotic cells; immunizing with the variable region; and isolating antibody specific for the variable region of the alpha subunit.
Claim 2
Independent Claim
76 words
A method for making an isolated antibody specific for the variable region of the alpha subunit of a mammalian T lymphocyte receptor, wherein the antibody is produced by the method comprising: expressing the variable region of the alpha subunit of the T lymphocyte receptor in a genetically engineered host selected from the group consisting of procaryotic and eucaryotic cells; immunizing with the variable region; and isolating antibody specific for the variable region of the alpha subunit.
Claim 3
Dependent Claim
23 words
The method of claim 1 wherein the variable region of the alpha subunit of the mammalian T lymphocyte receptor is an immunoglobulin-like domain.
Claim 4
Dependent Claim
23 words
The method of claim 1 wherein the animal is immunized with the isolated variable region of the alpha subunit or a portion thereof.
Claim 5
Dependent Claim
35 words
The method of claim 1 wherein cells producing the antibody are isolated and used to make hybridomas expressing monoclonal antibodies specific for the variable region of the alpha subunit of a mammalian T lymphocyte receptor.
Claim 6
Dependent Claim
12 words
The method of claim 1 wherein the antibody is a human antibody.
