Overview

Product name:	Mouse PF4(Platelet Factor 4) ELISA Kit
Reactivity:	Mouse
Alternative Names:	CXCL4; SCYB4; Chemokine C-X-C-Motif Ligand 4; Oncostatin-A; Iroplact
Assay Type:	Sandwich
Sensitivity:	0.068 ng/mL
Standard:	10 ng/mL
Detection Range:	0.16-10 ng/mL
Sample Type:	serum, platelet-poor plasma and cell culture supernates

Uniprot ID:	Q9Z126
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 PF4. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Mouse PF4. 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 PF4, 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 PF4 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 PF4 and the recovery rates were calculated by comparing the measured value to the expected amount of PF4 in samples.

Matrix	Recovery range	Average
serum(n=5)	80-95%	87%
EDTA plasma(n=5)	87-95%	91%
Heparin plasma(n=5)	82-97%	89%

線性

The linearity of the kit was assayed by testing samples spiked with appropriate concentration of PF4 and their serial dilutions. The results were demonstrated by the percentage of calculated concentration to the expected.
