Application This ELISA kit applies to the in vitro quantitative determination of Pg concentrations in serum, plasma, urine, saliva.

Test Principle

This ELISA kit uses the Competitive-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with Pg. During the reaction, Pg in the sample or standard competes with a fixed amount of Pg on the solid phase supporter for sites on the Biotinylated Detection Ab specific to Pg. Excess conjugate and unbound sample or standard are washed away, and Avidin-Horseradish Peroxidase (HRP) conjugate are added to each micro plate well and incubated. Then a TMB substrate solution is added to each well. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns from blue to yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The concentration of Pg in tested samples can be calculated by comparing the OD of the samples to the standard curve.

Technical Data


Intra-assay Precision (Precision within an assay): 3 samples with low, mid range and high level Pg were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): 3 samples with low, mid range and high level Pg were tested on 3 different plates, 20 replicates in each plate.

The recovery of Pg spiked at three different levels in samples throughout the range of the assay was evaluated in various matrices.

Sample Type Range (%) Average Recovery (%)
Serum(n=8) 80-94 84
EDTA plasma(n=8) 82-96 87
Urine(n=8) 85-109 95


Samples were spiked with high concentrations of Pg and diluted with Reference Standard & Sample Diluent to produce samples with values within the range of the assay.

  • Species:Human
  • Sample:serum
  • Sample source:serum
  • Detection result:good
  • Description:This ELISA Kit was used to assay normal human(women and men) serum by us. We operated procedure as Elabscience,s the instruction manual provided and the experimental results were very good------when the human serums were detected without dilution, the testing results were in the range of standard curve, what’s more, It is very near compared with the clinical assay kit! The Pg level of normal men serum is 0.1-3.5 ng/mL and the follicular phase women serum is 0.1-2.1 ng/mL.
