چکیده

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 by addition of 0.01% bovine serum albumin (BSA).

Standardization of an Enzyme-Linked Immunosorbent Assay for Detection of Infectious Bronchitis Virus Antibody.

An indirect enzyme–linked immunosorbent assay (ELISA) was developed for screening of antibody to avian infectious bronchitis virus (IBV). Antigen was prepared from whole-purified IBV Massachusetts serotype (BR 801 strain). Optimum dilution with minimum background for antigen concentration, rabbit anti-chicken conjugate and sera in developed ELISA was determined 0.1μg/ml, 1:3000 and 1:100, respe...

Expression of HA1 antigen of H5N1 influenza virus as a potent candidate for vaccine in bacterial system

The impending influenza virus pandemic requires global vaccination to prevent large-scale mortality and morbidity, but traditional influenza virus vaccine production is too slow for rapid responses. In this study, bacterial system has been developed for expression and purification of properly folded HA1 antigen as a rapid response to emerging pandemic strains. Here, a recombinant H5N1 (A/Indone...

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...

Stoichiometry of large T antigen and pp53 in complexes isolated from simian virus 40-transformed rat cells.

Simian virus 40-transformed cells synthesize high-molecular-weight protein complexes (22 to 30S) that consist of the virus-coded large T antigen (81,500 daltons) and the cellular antigen pp53. These complexes were partially purified from lysates of transformed rat cells by sucrose velocity sedimentation. The stoichiometry of the two proteins in the complex was studied by direct enzyme-linked im...
