Embryonic surface antigens: A “quasi-endodermal” teratoma antigen
Developmental Biology, 1976Abstract Hyperimmune antisera against a teratoma-derived endodermal carcinoma of the mouse were used in cytotoxicity tests and by absorption analysis to define a surface antigen. This antigen was found to be present on all tumor cells tested that were of endodermal origin as well as on embryonic liver, and was therefore designated “Endo.” Further ...

Murine Lymphocyte Surface Antigens
1979Publisher Summary This chapter discusses the multiple lymphocyte surface antigens of the mouse. A wide range of different antigens is described, ranging from those that have a broad tissue distribution to those highly restricted to specific lymphocytes and including others, such as viral-associated antigens.

Antigenic hybrids of influenza a viruses with surface antigens to order
Virology, 1970Abstract Stable antigenic hybrids between mammalian and avian strains of influenza A viruses with the hemagglutinin from one parent and the neuraminidase antigen from the other parent can be made to order in the allantois-on-shell system. Their isolation was made possible by the use of specific antisera to the hemagglutinin and neuraminidase antigens

Monoclonal antibodies and cell surface antigens
Cell Biology International Reports, 1979Antibody chains are encoded in three gene clusters containing genes for the variable and constant regions. V and C genes are separated in germ line and during differentiation a rearrangement takes place. But even after this rearrangement the V and C coding sequences are not contiguous.

The SV40 “S” Antigen and other Papovavirus-Induced Surface Antigens
1974Although a variety of properties which characterize virus-transformed animal cells (e.g., morphological changes, loss of growth control, agglutination by plant lectins) have been linked to surface membrane alterations (Black et al., 1971), perhaps the most important surface alteration which occurs in the transformed cell is that involving antigenic ...

A Surface Antigen Marker for Human Monocytes [PDF]
Antisera have been raised in rabbits against human peritoneal macrophages. After absorption with tonsil cells the sera reacted, by direct and indirect immunofluorescence, with phagocytic mononuclear cells from a variety of tissues and, in addition, stained a small population of nonphagocytic non‐T, non‐B mononuclear cells present in blood, spleen, and ...

The Journal of Immunology, 1975
Abstract Rat major histocompatibility or Ag-B antigen was isolated from soluble extracts of lymphoid cells by affinity chromatography. The purified antigen was shown in SDS gel electrophoresis to have a molecular weight of 30,000 to 35,000 daltons. In addition, amino acid composition was found to resemble, generally, that of HL-A and H-2

Differentiation Antigens of the Lymphocyte Cell Surface
Biochemical Society Transactions, 1976Many alloantigens and xenoantigens of lymphocytes are not found generally on other tissues, and this suggests that much of the lymphocyte cell surface is differentiated in comparison with other cell membranes. These differentiation antigens are probably molecules that mediate lymphocyte-specific functions, and are also of interest in that they provide ...

Journal of Cellular Physiology, 1979
AbstractIn the wild‐type strains, 156 and 168, of Paramecium primaurelia, the alleles G156 and G168 expressed at medium temperature specify two immunologically distinguishable surface antigens 156G and 168G, whose phenotypic expression shows allelic exclusion, the majority of heterozygotes being phenotypically [156G] while a small minority is ...

Melanocytes Express 3G5 Surface Antigen
The American Journal of Dermatopathology, 2004The 3G5-reactive ganglioside antigen (3G5 antigen) is expressed on the surface of various cell types including pericytes, pancreatic islet cells, thyroid follicular cells, and cells of the pituitary and the adrenal medulla. Expression on melanocytes has not yet been reported.
