Rabbit Progesterone ELISA Kit is a 90 minute competitive Enzyme-Linked Immunosorbent Assay (cELISA) designed for the rapid in vitro quantitative determination of rabbit Progesterone in serum and plasma.
Assay Type
Competitive (quantitative)
Principle of Assay
Rabbit Progesterone ELISA Kit (A327160) employs a rapid competitive Enzyme-Linked Immunosorbent Assay (ELISA) technique for the quantitative measurement of rabbit Progesterone in serum and plasma. Antigen specific for Progesterone has been pre-coated onto a 96-well microtiter plate. Standards and test samples are added to the wells together with HRP-conjugated detection reagent working solution. During incubation, Progesterone present in the sample competes with the immobilized antigen for binding to the HRP-conjugated detection reagent. Following incubation, unbound components are removed by washing. TMB substrate solution is then added to visualize the HRP enzymatic reaction, producing a blue-coloured product that changes to yellow following addition of acidic stop solution. The intensity of the yellow colour is inversely proportional to the concentration of Progesterone present in the sample. The concentration of Progesterone is determined by measuring the O.D. absorbance at 450 nm using a microplate reader and comparing the values to the standard curve.

Linearity assessment of the Rabbit Progesterone ELISA Kit (A327160) across serial sample dilutions. Linearity was evaluated using Serum and EDTA Plasma samples serially diluted from 1:2 to 1:16. Recovery (%) was calculated relative to the expected Rabbit Progesterone concentration at each dilution. Data are presented as mean recovery values from 8 replicates (n = 8).
Quick workflow summary for 90 Minute Competitive ELISA Kits. Standards or samples (50 µL per well) are added to antigen pre-coated microplate wells together with HRP-conjugated detection reagent working solution. During incubation, analytes present in the sample competitively inhibit binding of the HRP-conjugated reagent to the immobilized antigen coating. Following incubation and wash steps to remove unbound components, TMB substrate is added for color development. The enzymatic reaction is terminated using stop solution prior to optical density measurement at 450 nm. In this competitive ELISA format, signal intensity is inversely proportional to analyte concentration in the sample.
Streamlined rapid competitive ELISA workflow for fast and sensitive analyte quantification. This rapid 90-minute competitive ELISA workflow enables sensitive and reliable quantitative detection of target analytes in biological samples using a simplified incubation and detection protocol. Target analytes present in the sample compete with immobilized antigen for binding to specific detection antibodies during incubation. Following substrate development, colorimetric signal intensity is measured and is inversely proportional to analyte concentration within the sample. This optimized workflow supports high-performance ELISA analysis with reduced assay time and efficient sample processing.
