Enzyme immunoassay for oxytocin.
A competitive, double antibody enzyme immunoassay for oxytocin in a heterologous system was developed. Horseradish peroxidase was conjugated with oxytocin using N-succinimidyl 3-(2-pyridyldithio) propionate, and rabbit anti-oxytocin serum was produced by immunization of oxytocin-bovine serum albumin complex which was prepared by the carbodiimide method. The sensitivity of the assay was 4 microI...
متن کاملEnzyme immunoassay for gentamicin.
We describe a gentamicin assay in which a peroxidase-gentamicin conjugate competes with gentamicin for binding to a gentamicin antibody adsorbed to a polystyrene solid phase. The assay can be completed in 30 min and requires 50 microliter of diluted serum. The precision and accuracy are equivalent to that of a radioimmunoassay technique and the reagents are stable for several months.
متن کاملEvaluation of enzyme immunoassay and radioimmunoassay methods for the measurement of plasma oxytocin.
OBJECTIVE There is increased interest in measuring peripheral oxytocin levels to better understand the role of this peptide in mammalian behavior, physiology, and disease. The purpose of this study was to compare methods for plasma oxytocin measurement using a commercially available enzyme immunoassay (EIA) and radioimmunoassay (RIA), to evaluate the need for sample extraction, and to assess th...
متن کاملEnzyme immunoassay for carcinoembryonic antigen.
In this rapid, simple enzyme immunoassay for carcinoembryonic antigen (CEA) in serum the "sandwich" system is used. The CEA is first extracted from the serum into acetate buffer by heating at 70 degrees C, then incubated in a polyvinyl microtitration plate previously coated with anti-CEA. The bound CEA is then reacted with anti-CEA conjugated to horseradish peroxidase and the activity of the pe...
متن کاملEnzyme immunoassay for human ferritin.
We describe an enzyme immunoassay with use of beta-D-galactosidase for quantitation of ferritin in human serum. The minimum detectable ferritin concentration is 0.25 microgram/L of serum, which is comparable to results obtained by radioimmunoassay. The correlation coefficient between values determined by enzyme immunoassay and radioimmunoassay was 0.95 (n - 1 = 85, p less than 0.001).
