A solid-phase assay to screen monoclonal antibodies against DNA-binding protein.

چکیده
A method is described for selecting monoclonal antibodies (mAb) against DNA-binding protein. The protocol involves a non-radioactive solid-phase DNA binding assay using a 96-well plate. Because the solid-phase assay is highly specific and sensitive, partially purified antigen is sufficient for the immunization, and mAb screening can be performed with crude cell extract as the antigen. MAbs obtained by this method could supershift the DNA-protein complex in the electromobility shift assay, and were sufficient for immunoscreening of a cDNA expression library.

Background & Aims: Toxoplasma gondii is an obligate, intracellular parasite, which is widely spread in the world. The parasite is able to infect all warm-blooded hosts including humans and farm animals. The infection in humans often occurs after the ingestion of raw or undercooked meat containing tissue cysts. Several methods have been applied to detect this parasite in contaminated foods. Reco...

Epitope-G1 of bovine ephemeral fever virus (BEFV) G glycoprotein has been genetically and antigenically conserved among various isolates of BEFV and only reacts with anti-BEFV neutralising antibodies. Therefore, it is a candidate antigen for development of the enzyme linked immunosorbent assay (ELISA) for serological identification bovine ephemeral fever (BEF)-infected animals. The aim of this ...
متن کاملUse of monoclonal antibodies to identify shared idiotypes on human antibodies to native DNA from patients with systemic lupus erythematosus.
Antinative DNA antibodies were purified from the serum of a patient with active systemic lupus erythematosus. Using hybridoma technology, we produced several mouse monoclonal antibodies directed against idiotypic determinants on these antinative DNA antibodies. One of these monoclonal anti-idiotypic antibodies, 3I, an IgG2a Kappa, was extensively characterized. 3I is believed to be directed aga...
