Overview

Product name: Human Anti-OV Ab(Anti-Ovarian Antibody) ELISA Kit
Reactivity: Human
Alternative Names: Ovarian antibody
Assay Type: Sandwich
Sensitivity: 0.49 U/mL
Standard: 100 U/mL
Detection Range: 1.57-100 U/mL
Sample type: serum, plasma and biological fluids
Assay length: 3.5h
Research Area: Infection immunity;
Test principle: The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Human Anti-OV Ab. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human Anti-OV Ab. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Human Anti-OV Ab, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. 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 Human Anti-OV Ab 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 Anti-OV Ab and the recovery rates were calculated by comparing the measured value to the expected amount of Anti-OV Ab in samples.
Matrix Recovery range Average
serum(n=5) 80-97% 88%
EDTA plasma(n=5) 82-98% 90%
Heparin plasma(n=5) 82-94% 88%

Linearity

The linearity of the kit was assayed by testing samples spiked with appropriate concentration of Anti-OV Ab 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) 83-92% 96-102% 81-93% 79-91%
EDTA plasma(n=5) 86-93% 91-105% 87-98% 89-94%
Heparin plasma(n=5) 88-95% 98-107% 90-99% 88-97%
