Mouse PHF8(PHD Finger Protein 8) ELISA Kit

Overview

Product name: Mouse PHF8(PHD Finger Protein 8) ELISA Kit
Reactivity: Mouse
Alternative Names: ZNF422; MRXSSD; JHDM1F; Jumonji C Domain-Containing Histone Demethylase 1F; Histone lysine demethylase PHF8
Assay Type: Sandwich
Sensitivity: 0.118 ng/mL
Standard: 20 ng/mL
Detection Range: 0.32-20 ng/mL
Sample Type: Tissue homogenates and other biological fluids.
Assay Length: 3.5h
Research Area: Signal transduction;
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 Mouse PHF8. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Mouse PHF8. 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 Mouse PHF8, 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 Mouse PHF8 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 PHF8 and the recovery rates were calculated by comparing the measured value to the expected amount of PHF8 in samples.
Matrix Recovery range Average
serum(n=5) 95-107% 101%
EDTA plasma(n=5) 82-95% 88%
Heparin plasma(n=5) 88-102% 95%

Linearity

The linearity of the kit was assayed by testing samples spiked with appropriate concentration of PHF8 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% 89-99% 85-95%
EDTA plasma(n=5) 88-104% 86-102% 79-93% 89-97%
Heparin plasma(n=5) 87-98% 85-96% 92-102% 81-93%
