Effect of hyperthermia on murine cell surface histocompatibility antigens.
The effect of heat on the density of cell surface histocompatibility antigens was examined. Antigen density and distribution were determined by radioimmunoassay and flow cytometry after the binding of radioiodinated or fluoresceinated monoclonal antibody (anti-H-2Kk and anti-H-2Kb) to murine lymphoma cells in suspension cultures. Antibody binding was unaffected by temperatures between 37 degree...
متن کاملPurification, subunit structure, and partial amino acid sequence of metapyrocatechase.
The enzyme anthranilate-5-phosphoribosylpyrophosphate phosphoribosyltransferase from Serratia marcescens was purified to apparent homogeneity. The purification procedure included ammonium sulfate precipitation, DEAE-cellulose chromatography, Sephadex gel filtration and hydroxyapatite chromatography. The molecular weight of the native protein as determined on a calibrated Sephadex G-200 column w...
متن کاملStructure and evolution of transplantation antigens: partial amino-acid sequences of H-2K and H-2D alloantigens.
Techniques for the amino acid sequence analysis of subnanomole quantities of polypeptides have been applied to characterize beta2-microglobulin and transplantation antigens of the mouse isolated from spleen cells by indirect immunoprecipitation. Eleven residues were identified throughout the NH2-terminal 27 residues of the beta2-microglobulin; all were identical to residues seen at the correspo...
متن کاملStructure of murine Ia antigens: partial NH2-terminal amino acid sequences of products of the I-E or I-C subregion.
Partial amino acid sequence of the Ia molecule encoded by the I-E or I-C (I-EC) subregion of the major histocompatibility complex of the mouse are presented. The Ia molecule appears to be comprised of two noncovalently associated polypeptides. The larger subunit, alpha, has an approximate molecular weight of 35,000 and the smaller subunit, beta, an approximate molecular weight of 28,000. Severa...
