Mouse 8-iso-PGF2α(8-isoprostane)ELISA Kit

Overview

Product name: Mouse 8-iso-PGF2α(8-isoprostane) ELISA Kit
Reactivity: Mouse
Alternative Names: 8-isoprostane; 8-iso-PGF2α
Assay Type: Competitive Inhibition
Sensitivity: 9.375 pg/mL
Standard: 1000 pg/mL
Range: 15.625-1000 pg/mL
Sample Type: serum, plasma and other biological fluids

Test principle: This assay employs the competitive inhibition enzyme immunoassay technique. The microtiter plate provided in this kit has been pre-coated with Mouse 8-iso-PGF2α protein. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Mouse 8-iso-PGF2α. 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 Mouse 8-iso-PGF2α in the samples is then determined by comparing the OD of the samples to the standard curve.

Precision

Intra-assay Precision (Precision within an assay)：CV%<8%

Three samples of known concentration were tested twenty times on one plate to assess intra-assay precision.

Inter-assay Precision (Precision between assays)：CV%<10%

Three samples of known concentration were tested in forty separate assays to assess inter-assay precision.

Recovery

Matrices listed below were spiked with certain level of recombinant 8-iso-PGF2α and the recovery rates were calculated by comparing the measured value to the expected amount of 8-iso-PGF2α in samples.
Matrix Recovery range Average
serum(n=5) 90-105% 97%
EDTA plasma(n=5) 87-99% 93%
Heparin plasma(n=5) 82-95% 87%

Linearity

The linearity of the kit was assayed by testing samples spiked with appropriate concentration of 8-iso-PGF2α and their serial dilutions. The results were demonstrated by the percentage of calculated concentration to the expected.
Matrix 1:2 1:4 1:8 1:16
serum(n=5) 85-94% 87-101% 79-96% 85-99%
EDTA plasma(n=5) 95-104% 82-96% 92-105% 83-92%
Heparin plasma(n=5) 95-104% 84-98% 95-102% 88-102%
