SKU: orb2667393

Description

The Rat Prostaglandin E2 (PGE2) ELISA Kit is designed to quantify Prostaglandin E2 (PGE2) in rat serum, plasma and other biological fluids. The kit has a detection range of 31.25-2000 pg/mL and a sensitivity of 11.2 pg/mL.

Research Area

Infectious Disease & Virology, Metabolism Research

Images & Validation

• Tested Applications: ELISA
• Application Notes:
  This assay employs the competitive inhibition enzyme immunoassay technique. The microtiter plate provided in this kit has been pre-coated with Rat PGE2. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Rat PGE2. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of Rat PGE2 in the samples is then determined by comparing the OD of the samples to the standard curve.

Procedure & Performance

• Assay Principle:
  This kit is based on a competitive ELISA detection method. The microtiter plate is pre-coated with target antigen. During the assay, the target antigen in the sample or standard competes with the immobilized target for binding sites on the biotinylated detection antibody specific to the target antigen. After incubation, excess conjugate and unbound sample or standard are removed by washing. HRP–streptavidin (SABC) is then added to each well and incubated, followed by the addition of TMB substrate solution. The enzymatic reaction is terminated by adding an acidic stop solution, and the color change is measured at 450 nm using a microplate reader. The concentration of the target antigen in the samples is determined by comparison with the standard curve and is inversely proportional to the OD450 value.

• Calculation of Results:
  1. Average the duplicate readings for each Standard, Control, and Sample, and subtract the mean optical density of the zero Standard. ; 2. Construct a standard curve by plotting the target concentration on the y-axis against absorbance on the x-axis and draw a curve through the data points. ; 3. Determine the sample concentration by substituting the OD450 value into the standard curve. For diluted samples, multiply the calculated value by the corresponding dilution factor.
