Removal of an endogenous antigen from an antibody to increase its effective affinity constant, as illustrated by triiodothyronine assay.

چکیده
Antisera to triiodothyronine were shown to contain large quantities of the hormone, well in excess of normal circulating concentrations. Extracting the triiodothyronine from the antiserum with alkaline ethanol yielded an antibody of increased affinity. Use of this antibody in a radioimmunoassay resulted in a fourfold increase in sensitivity as compared with the unextracted material.

Measurement of Affinity Constant of Anti-human IgG Monoclonal Antibodies by an ELISA-based Method
Background: The affinity of an antibody to its antigen is a crucial parameter in its biological activity and performance of an immunoassay such as ELISA. Affinity of most IgG specific MAbs are often determined by methods which require labeling of either antigen or antibody, and are sometimes difficult to control, do not always lead to the expected signal and often result in immunological modifi...

Background: Ofatumumab, an anti-CD20 mAb, was approved in 2009 for the treatment of chronic lymphocytic leukemia. This mAb acts through immune-mediated mechanisms, in particular complement-dependent cytotoxicity and antibody-dependent cellular cytotoxicity by natural killer cells as well as antibody-dependent phagocytosis by macrophages. Apoptosis induction is another mechanism of this antibody...

Background: Although a simple and direct method does not exist for the detection of chlamydial infections, there are situations in which reliable serological tests, with sensi-tivity related to a specific antigen, could be helpful. Objective: The aim of this study was to clone the first 1100 bp of the C. trachomatis outer membrane protein 2 (omp2) gene in order to prepare a recombinant protein ...
متن کاملSerological Evaluation of Experimental Toxoplasma gondii Infection in Cats by Using Immunoblotting Based on an Affinity Purified Surface Antigen
Toxoplasma gondii is an apicomplexan parasite that infects human and almost all warm-blooded animals. The life cycle of the parasite includes an asexual reproduction in intermediate hosts (Mammals and birds) and a sexual reproduction in definitive hosts (Felidae). Cats are both the intermediate and the definitive host for T. gondii. The aim of this study was to investigate anti-T. gondii antibo...
