Isolation and purification of HLA-DR antigen from Daudi cell line by immunoaffinity chromatography
Introduction: The major histocompatibility complex (MHC) is a group of cell surface proteins that are essential for recognizing foreign molecules in human and other mammals. The physiologic function of MHC molecules is the presentation of peptides to T cells. In this study, we evaluated the purification of a class II MHC molecule (HLA-DR) from a human Burkitt′s lymphoma cell line; Daudi...

متن کاملPartial purification of Simian virus 40 large T antigen by immunoaffinity chromatography and its detection by enzyme-linked immunosorbent assay.
Simian virus 40 (SV40) large T antigen was partially purified from small amounts of SV40-infected and SV40-transformed cells by immunoaffinity chromatography with high recovery. T antigen, in both crude and partially purified states, was detected rapidly by a sensitive and quantitative enzyme-linked immunosorbent assay (ELISA). Stability of the partially purified T antigen was found to increase...
متن کاملComplexes of polyoma virus medium T antigen and cellular proteins.
Antibodies against synthetic peptides corresponding to the carboxyl-terminal six amino acids, Lys-Arg-Ser-Arg-His-Phe (KF), and an internal region, Glu-Glu-Glu-Glu-Tyr-Met-Pro-Met-Glu (EE), of polyoma virus medium T antigen were used successively to purify medium T antigen by affinity chromatography. Medium T antigen from cell extracts was first bound to anti-KF antibodies and released from the...
متن کاملPurification of nucleotide-requiring enzymes by immunoaffinity chromatography.
Monospecific (affinity-purified) anti-(yeast glucose-6-phosphate dehydrogenase) IgG inhibits three different NADPH-requiring enzymes, chicken liver dihydrofolate reductase, pigeon liver fatty acid synthetase and chicken liver malic enzyme. The inhibition of all three enzymes was approx. 50% in a 2h incubation with 100 micrograms of IgG. Similarly, with several different NADH-requiring enzymes, ...
