Five mAbs have been generated and used to characterize TAP (T cell activating protein) a novel, functional murine T cell membrane antigen. The TAP molecule is a 12-kD protein that is synthesized by T cells. By antibody crossblocking, it appears to be closely associated with a 16-kD protein on the T cell membrane also identified with a novel mAb. These(More)
Here we characterize the T-cell-activating protein (TAP), an Ly-6 gene product involved in T cell activation, as a glycoprotein with a molecular weight of 10-12 kd under nonreducing conditions and 15-18 kd under reducing ones. Two of the three bands that are precipitated from metabolically labeled cells are expressed on the cell surface and can be recovered(More)
TAP is a phosphatidylinositol-anchored membrane protein that is involved in murine T lymphocyte activation. To determine the relationship between TAP and T cell receptor/CD3-mediated activation, we derived TAP expression mutants of a T-T hybridoma. Two phenotypically distinct classes of mutants were obtained. The first has a selective defect in the(More)
Extraction and purification of nucleic acids from complex biological samples for PCR are critical steps because inhibitors must be removed that can affect reaction efficiency and the accuracy of results. This preanalytical processing generally involves capturing nucleic acids on microparticles that are then washed with a series of buffers to desorb and(More)
Medullary, peanut agglutinin-negative (PNA-), thymocytes were activated in vitro with either exogenous interleukin 1 (IL-1) or accessory cells. T cell blasts from these cultures were subsequently fused to BW5147 to generate thymocyte hybridomas. Fusion frequencies similar to those obtained with peripheral T lymphocytes were observed. A high frequency of(More)
