Recovery

Matrices listed below were spiked with certain level of recombinant Serum Amyloid A (SAA) and the recovery rates were calculated by comparing the measured value to the expected amount of Serum Amyloid A (SAA) in samples.

Matrix Recovery range (%) Average(%)
serum(n=5) 80-97 82
EDTA plasma(n=5) 91-98 94
heparin plasma(n=5) 91-98 95

Precision

Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Serum Amyloid A (SAA) were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Serum Amyloid A (SAA) 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 Serum Amyloid A (SAA) 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) 84-103% 80-95% 85-101% 79-90%
EDTA plasma(n=5) 82-89% 91-99% 96-104% 82-92%
heparin plasma(n=5) 80-101% 89-96% 83-104% 83-94%

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.

ELISA Kit for Serum Amyloid A (SAA)

Test principle

This assay employs the competitive inhibition enzyme immunoassay technique. A monoclonal antibody specific to Serum Amyloid A (SAA) has been pre-coated onto a microplate. A competitive inhibition reaction is launched between biotin labeled Serum Amyloid A (SAA) and unlabeled Serum Amyloid A (SAA) (Standards or samples) with the pre-coated antibody specific to Serum Amyloid A (SAA). After incubation the unbound conjugate is washed off. Next, avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. The amount of bound HRP conjugate is reverse proportional to the concentration of Serum Amyloid A (SAA) in the sample. After addition of the substrate solution, the intensity of color developed is reverse proportional to the concentration of Serum Amyloid A (SAA) in the sample.
