Overview

Product name:	EasyStep Rat vWF(Von Willebrand Factor) ELISA Kit
Reactivity:	Rat
Alternative Names:	F8VWF; VWD; von Willebrand antigen 2
Assay Type:	Sandwich
Sensitivity:	41 ng/mL
Standard:	10 μg/mL
Detection Range:	0.16-10 μg/mL
Sample Type:	Serum, plasma
Assay Length:	1.5h
Research Area:	Signal transduction;Hematology;
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 vWF, and the Rat vWF standard plate wells that pre-coated using protein-related techniques are provided separately. Standard/Sample Diluent Buffer or samples are added to the appropriate microtiter plate wells ,then added a HRP-conjugated antibody specific to Rat vWF. After TMB substrate solution is added, only those wells that contain Rat vWF and HRP-conjugated antibody 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 vWF in the samples is then determined by comparing the OD of the samples to the standard curve.

细密度

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.

接纳率

Matrices listed below were spiked with certain level of recombinant vWF and the recovery rates were calculated by comparing the measured value to the expected amount of vWF in samples.

Matrix	Recovery range	Average
serum(n=5)	87-99%	93%
EDTA plasma(n=5)	81-95%	88%
Heparin plasma(n=5)	87-99%	93%

线性

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