Overview

Product name:	Human HSP90α(Heat Shock Protein HSP 90-alpha) ELISA Kit
Reactivity:	Human
Alternative Names:	heat shock protein 90 alpha family class A member 1; HSP90AA1; HSPCA
Assay Type:	Sandwich
Sensitivity:	0.53 ng/mL
Standard:	100 ng/mL
Detection Range:	1.56-100 ng/mL
Sample type:	serum, plasma, tissue homogenates
Assay length:	3.5h
Research Area:	Neuro science,Stress response
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 HSP90α. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human HSP90α. 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 HSP90α, 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 HSP90α 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 HSP90α and the recovery rates were calculated by comparing the measured value to the expected amount of HSP90α in samples.

Matrix	Recovery range	Average
serum(n=5)	83-96%	89%
EDTA plasma(n=5)	92-107%	99%
Heparin plasma(n=5)	80-93%	86%

线性

The linearity of the kit was assayed by testing samples spiked with appropriate concentration of HSP90α and their serial dilutions. The results were demonstrated by the percentage of calculated concentration to the expected.
