Overview

Product name:	Rat GFAP(Glial Fibrillary Acidic Protein) ELISA Kit
Reactivity:	Rat

Assay Type:	Sandwich
Sensitivity:	26.1 pg/mL
Standard:	4000 pg/mL
Detection Range:	62.5-4000 pg/mL
Sample Type:	serum, plasma, tissue homogenates, cell lysates, cell culture supernates and other biological fluids
Assay Length:	3.5h

Uniprot ID:	P47819
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 Rat GFAP. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Rat GFAP. 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 Rat GFAP, 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 Rat GFAP 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 GFAP and the recovery rates were calculated by comparing the measured value to the expected amount of GFAP in samples.

Matrix	Recovery range	Average
serum(n=5)	78-90%	84%
EDTA plasma(n=5)	92-106%	99%
Heparin plasma(n=5)	90-105%	97%

線性

The linearity of the kit was assayed by testing samples spiked with appropriate concentration of GFAP and their serial dilutions. The results were demonstrated by the percentage of calculated concentration to the expected.
