Amphetamines in hair by enzyme-linked immunosorbent assay.
Human hair was collected from the occipital crown region of the head from several subjects; these hair samples were presumptively positive for amphetamines by a previously evaluated immunoassay. Hair was washed briefly with methanol to remove external contamination, then extracted with hot methanol for 2 h to recover the drugs. The extracts were evaporated to dryness, reconstituted in buffer, a...
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...
متن کاملenzyme-linked immunosorbent assay
An enzyme-linked immunosorbent assay was used to titrate antisera raised against live cultures of eight type species (biotypes) of Bacteroides with the EDTA-released outer-membrane complex from 29 characterized strains of Bacteroides species. With only minor exceptions, the strains investigated reacted to titre with the antisera raised against the homologous type species and not against the het...
متن کاملImmunodiagnosis of Haemonchus contortus infection in sheep by indirect enzyme linked immunosorbent assay (ELISA)
Indirect plate enzyme-linked immunosorbent assay was standardized and evaluated for its effectivenessin immunodiagnosis of haemonchosis in experimental and clinical cases in sheep by using somatic wholeadult antigen of H. contortus. Plate ELISA was standardized using 5 μg/well antigen concentration with1:100 and 1:1000 of sera and conjugate dilution. Indirect plate ELISA was able to demonstrate...
متن کاملAntigens by Enzyme-Linked Immunosorbent Assay
A new type of immunoassay (enzyme-linked immunosorbent assay, ELISA) has been used for the detection of antibodies against Salmonella 0 antigens. The results show that ELISA is specific and highly sensitive. When compared with the Widal reaction, passive hemagglutination, and quantitative precipitation, ELISA was shown to be more sensitive. In addition, immunoglobulin G and immunoglobulin M ant...
