Our purpose was to develop and characterize an enzyme-linked immunosorbent assay (ELISA) which could measure the concentration of amphotericin B in serum. Amphotericin B was assayed by competition ELISA. Multiwell ELISA plates coated with amphotericin B (1.0 micrograms/ml) conjugated to bovine serum albumin were used to test replicates of serum samples spiked with amphotericin B. Purified rabbi...
A sensitive and specific enzyme-linked immunosorbent assay for an antiarrhythmic drug, amiodarone (AMI), was developed, which is capable of measuring levels as low as 16 ng/ml. Anti-AMI antibody was obtained by immunizing rabbits with an antigen conjugated with bovine serum albumin using diazotized 4-amino-1-(2-diethylaminoethoxy)-2,6-diiodobenzene. Enzyme labeling of AMI with beta-D-galactosid...
BACKGROUND The presence of food-specific IgG antibodies in human serum may be useful for diagnosis of adverse food reactions. However, the clinical utility of testing for such antibodies remains very controversial. The aim of this study was to evaluate the serum levels and population distribution of food-specific IgGs and their association with chronic symptoms in a large-scale Chinese populati...
OBJECTIVE Progesterone-induced blocking factor (PIBF) may be the mediator of the pregnancy maintenance effects of progesterone. The aim of this study is to investigate the potential value of measuring the maternal serum concentration of PIBF at 11-13 weeks' gestation in the prediction of spontaneous early preterm delivery. METHOD The maternal serum concentration of PIBF at 11-13 weeks was mea...
Cortisol mouse monoclonal antibodies were produced and characterized. Of the four clones studied, supernatant from one clone (A2), compared with other cortisol monoclonal antibodies, showed minimal cross-reactivity to other C21 steroids and was suitable for the direct determination of cortisol in plasma by enzyme-linked immunosorbent assay using a standard 96-well microtiter plate. The enzyme-l...
