Enzyme-linked immunosorbent assay (ELISA) to detect antibodies in gonorrhea using whole cells.
The choice of an antigen that will adequately differentiate between infected and non-infected patients has been a problem in detecting gonococcal antibodies for diagnosis. We have used the sensitive technique of ELISA to test various serotypes of Neisseria gonorrhoeae for their suitability as antigens. Whole cells of each serotype were attached to polystyrene plates using poly-L-lysine, N gonor...
متن کاملRapid enzyme-linked immunosorbent assay (ELISA) for Aspergillus fumigatus antibodies.
A rapid enzyme-linked immunosorbent assay (ELISA) where component incubation periods were shortened to one hour, was compared with agar gel double diffusion (AGDD) and a standard ELISA procedure for detecting antibodies to Aspergillus fumigatus in 28 asthmatic patients with suspected allergic aspergillosis. Using two A fumigatus antigens the rapid ELISA compared well with AGDD and the standard ...
متن کاملDevelopment and evaluation of an enzyme-linked immunosorbent assay (ELISA), using chlamydial group antigen, to detect antibodies, to Chlamydia trachomatis.
Chlamydial group antigen was extracted from Chlamydia trachomatis strain SA2(f) and used as the antigen for an ELISA. The assay was reproducible since chlamydial antibody titres differed by no more than twofold when sera were tested on up to eight occasions. In tests on sera from 75 patients attending venereal disease or rheumatology clinics, the results of the ELISA and of a microimmunofluores...
متن کاملThe ELISA, enzyme-linked immunosorbent assay.
Featured Article: Engvall E, Perlmann P. Enzymelinked immunosorbent assay (ELISA). Quantitative assay of immunoglobulin G. Immunochemistry 1971;8:871– 4. This paper was my first as a graduate student of Professor Peter Perlmann at Stockholm University. At the time, RIAs were in full bloom, but they were too sophisticated for many areas of research and diagnosis because they required expensive e...
متن کاملENZYME-LINKED IMMUNOSORBENT ASSAY OF NEOPTERIN USING PENICILLINASE AS LABEL
An enzyme-linked immunosorbent assay for neopterin using penicillinase as marker enzyme is reported here by polyclonal antibodies against neopterin conjugated to bovine serum albumin which were raised in rabbits. Immunoglobulin fractions were purified and coated on wells of microtiter plates. A chain heterology was introduced in neopterin derivative and conjugated to penicillinase. The assa...
