ELISA Kit for Heat Shock Protein 70 (HSP70)

DnaK; 70 Kilodalton Heat Shock Proteins

Specificity

This assay has high sensitivity for detection of Heat Shock Protein 70 (HSP70).
100% cross-reactivity of Heat Shock Protein 70 (HSP70) was observed among Bovine, Caprine, Ovine.

Recovery

Matrices listed below were spiked with certain level of recombinant Heat Shock Protein 70 (HSP70) and the recovery rates were calculated by comparing the measured value to the expected amount of Heat Shock Protein 70 (HSP70) in samples.

Matrix Recovery range (%) Average(%)
serum(n=5) 82-103 91
EDTA plasma(n=5) 80-101 85
heparin plasma(n=5) 91-105 98

Precision

Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Heat Shock Protein 70 (HSP70) were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Heat Shock Protein 70 (HSP70) were tested on 3 different plates, 8 replicates in each plate.
CV(%) = SD/meanX100
Intra-Assay: CV<10%
Inter-Assay: CV<12%

Linearity

The linearity of the kit was assayed by testing samples spiked with appropriate concentration of Heat Shock Protein 70 (HSP70) and their serial dilutions. The results were demonstrated by the percentage of calculated concentration to the expected.

Sample 1:2 1:4 1:8 1:16
serum(n=5) 96-105% 78-95% 89-96% 79-101%
EDTA plasma(n=5) 90-104% 95-102% 94-103% 78-103%
heparin plasma(n=5) 86-94% 78-98% 89-103% 82-99%

Stability

The stability of kit is determined by the loss rate of activity. The loss rate of this kit is less than 5% within the expiration date under appropriate storage condition.
To minimize extra influence on the performance, operation procedures and lab conditions, especially room temperature, air humidity, incubator temperature should be strictly controlled. It is also strongly suggested that the whole assay is performed by the same operator from the beginning to the end.
