The monoclonal antibody CR11-351 discriminates HLA-A2 variants identified by T cells
Serologic and immunochemical assays have shown that the monoclonal antibody (MoAb) CR11-351 recognizes a determinant expressed by HLA-A2 and A28 alloantigens. The MoAb CR1 1-351 blocks the cytotoxicity of some...

Stimulation of human T lymphocytes by PHA-activated autologous T lymphocytes: Analysis of the role of Ia-like antigens with monoclonal antibodies
Human T lymphocytes activated with PHA express Ia-like antigens and acquire the ability to stimulate autologous T lymphocytes in mixed lymphocyte reaction. This reaction is immunological in nature since it has...

The monoclonal xenoantibody Q6/64 recognizes a determinant expressed by certain gene products of the A and B loci of the HLA region
A combination of serological (cytotoxicity, binding assay, lysostrip) and immunochemical (indirect immunoprecipitation, sequential immunoprecipitation, two-dimensional gel electrophoresis) assays have shown th...

Human Ia-like antigens
Analysis of the tissue distribution of human Ia-like antigens has shown that they have a wider distribution than originally reported. Furthermore, the expression of Ia-like antigens may change when cells under...

Immunochemical analysis of anti-HLA-A2, HLA-A3, and HLA-B27 xenoantisera elicited with hybrids between human and murine cells
Rabbits were immunized with hybrids constructed with human and murine cells. Serological and immunochemical studies showed that xenoantiserum 1595 is operationally specific for HLA-A2, xenoantisera 0806 and 07...

The free and the β2-microglobulin-associated heavy chains of HLA-A, B alloantigens share the antigenic determinant recognized by the monoclonal antibody Q1/28
Serological and immunochemical assays have shown that the monoclonal antibody Q1/28 recognizes an antigenic determinant which is expressed on the heavy chain of subsets of HLA-A, B antigens and is distinct fro...

Cross-reactivity between human and murine lymphocyte antigens
The anti-H-2 alloantiserum D-32 [(BlO.A(2R) × C3H.SW) anti-C3H] is cytolytic to human lymphocytes. Fab2 blocking assays, indirect immunoprecipitation and sequential immunoprecipitation experiments showed that the...

Structural Analyses of HLA-DR Antigens
There has been considerable progress in the characterization of HLA-DR antigens even though these human counterparts of murine and guinea pig Ir gene products were identified only a few years ago. The information...

Human lymphoid cell lines as targets for DRw
Cultured human lymphoid cell lines (LCL) are useful as a source of target cells in several immunologic assays. More recently such cells have been used for the serological characterizations of the HLA-DR antige...

Structural relationship between W4/W6 antigens and other surface markers on cultured human lymphoid cells as determined by the ‘lysostrip’ method
The structural relationship of histocompatibility antigens W4 and W6 with other surface markers on cultured human lymphoid cells of the B type has been investigated, utilizing the lysostrip technique. W4 and W...

Evidence for linkage between HLA antigens and receptors for complement components C3b and C3d in human-mouse hybrids
A linkage between HLA-A and HLA-B antigens and receptors for complement components C3b and C3d has been demonstrated by means of human-mouse somatic cell hybridization. In 26 hybrid clones formed between the h...
