Description

This ELISA kit uses the Sandwich-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Human TWEAK. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Human TWEAK and Avidin-Horseradish Peroxidase (HRP) conjugate are added successively to each micro plate well and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain Human TWEAK, biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. The enzyme-substrate reaction is terminated by the addition of stop solution and the color tus yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The OD value is proportional to the concentration of Human TWEAK. You can calculate the concentration of Human TWEAK in the samples by comparing the OD of the samples to the standard curve.

Detection Method

Colormetric

Recovery

80%-120%. The recovery of Human TWEAK spiked at three different levels in samples throughout the range of the assay was evaluated in various matrices.

Sample Type	Range (%)	Average Recovery (%)
Serum(n=8)	99-110	105
EDTA plasma (n=8)	96-107	102
Cell culture media (n=8)	87-98	94

Specificity

This kit recognizes Human TWEAK in samples. No significant cross-reactivity or interference between Human TWEAK and analogues was observed.

Sample Type

Serum, Plasma, Other biological fluids

Precision

Both intra-CV and inter-CV are < 10%.
Intra-assay Precision (Precision within an assay): 3 samples with low, mid range and high level Human TWEAK were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): 3 samples with low, mid range and high level Human TWEAK were tested on 3 different plates, 20 replicates in each plate.
