Overview

Product name: Mouse Phospho AKT S473 (p-AKT) ELISA Kit
Reactivity: Mouse
Alternative Names: p-AKT
Assay Type: Sandwich
Sensitivity: 49.6 pg/mL
Standard: 10000 pg/mL
Detection Range: 156.25-10000 pg/mL
Sample Type: tissue homogenates, cell lysates and other biological fluids
Assay Length: 3.5h
Research Area: Enzyme & Kinase;
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 p-AKT. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Mouse p-AKT. 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 p-AKT, 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 p-AKT 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 p-AKT and the recovery rates were calculated by comparing the measured value to the expected amount of p-AKT in samples.
Matrix Recovery range Average
serum(n=5) 78-95% 86%
EDTA plasma(n=5) 89-105% 97%
Heparin plasma(n=5) 86-99% 92%

Linearity

The linearity of the kit was assayed by testing samples spiked with appropriate concentration of p-AKT 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) 91-102% 79-91% 89-103% 82-95%
EDTA plasma(n=5) 79-92% 87-103% 79-96% 92-105%
Heparin plasma(n=5) 85-92% 96-103% 87-98% 95-106%
