Overview 文獻(xiàn)

Product name: Human ALP(Alkaline Phosphatase) ELISA Kit
Reactivity: Human
Alternative Names: AKP; ALKP; Basic Phosphatase
Assay Type: Sandwich
Sensitivity: 0.067 ng/mL
Standard: 10 ng/mL
Detection Range: 0.16-10 ng/mL
Sample Type: serum, plasma, tissue homogenates and other biological fluids
Assay Length: 3.5h
Research Area: Enzyme & Kinase;Metabolic pathway;Tumor immunity;Infection immunity;Hepatology;Bone metabolism;
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 ALP. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human ALP. 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 ALP, 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 ALP in the samples is then determined by comparing the OD of the samples to the standard curve.

精密度

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.

回收率

Matrices listed below were spiked with certain level of recombinant ALP and the recovery rates were calculated by comparing the measured value to the expected amount of ALP in samples.
Matrix Recovery range Average
serum(n=5) 88-102% 95%
EDTA plasma(n=5) 95-108% 101%
Heparin plasma(n=5) 83-96% 89%

線性

The linearity of the kit was assayed by testing samples spiked with appropriate concentration of ALP 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) 87-102% 82-91% 86-93% 81-94%
EDTA plasma(n=5) 85-92% 79-96% 89-101% 85-97%
Heparin plasma(n=5) 86-94% 93-102% 89-97% 85-94%
