Comparison of calcitonin determinations by polyclonal and monoclonal IRMAs.
To the Editor: Serum calcitonin (CT) has important diagnostic and prognostic value in patients with medullary thyroid carcinoma (MTC). Although CT can be routinely quantified by a variety of 2-site immunoassays, different assays may yield very different results. This variability, particularly at low CT concentrations, led to the recommendation to use reliable and sensitive assays in the screeni...
متن کاملComparison of monoclonal and polyclonal enzyme immunoassays for carcinoembryonic antigen.
A new commercially available CEA immunoassay, using monoclonal antibody, was evaluated for the purpose of routine clinical use. The between-day coefficient of variation was 5.2% at the 6.6 micrograms/l level and 4.1% at the 14.2 micrograms/l level. The results of analysis of sera from 260 patients were compared with the data from an established method with polyclonal antiserum. A good correlati...
متن کاملMonoclonal and polyclonal antisera
The extensive application of the hybridoma technology for tissue phenotyping has demonstrated in the last decade that a number of heterodimeric molecules consisting of noncovalently associated α and β subunits (Hynes, 1992), named integrins, play a major role in cell-to-cell and cellto-interstitium interactions as well as in cell trafficking (Hemler, 1990; Albelda and Buck, 1990). The structura...
متن کاملPolyclonal and monoclonal antibodies.
The breadth of repertoire yet beautiful specificity of the antibody response is the key to its physiological efficacy in vivo; it also underpins the attractiveness of antibodies as laboratory and clinical reagents. One aspect of the body's reaction to invasion by a microorganism is the activation and clonal expansion of antigen-reactive B lymphocytes. Once these have matured into plasma cells, ...
متن کاملMonoclonal Antibodies and Polyclonal Antibodies: A Brief Comparison
It is called an immunoglobulin that is used for neutralization of the foreign pathogens like viruses, bacteria or any foreign bodies invade the blood. When antibodies produced from immunized animals against certain antigen will produce what is called polyclonal antibodies (PAbs) which are mixture of different antibodies produced by many different B cell clones that identify different epitopes (...
