Matrices listed below were spiked with certain level of recombinant Apolipoprotein A1 (APOA1) and the recovery rates were calculated by comparing the measured value to the expected amount of Apolipoprotein A1 (APOA1) in samples.

Matrix Recovery range (%) Average(%)
serum(n=5) 78-96 93
EDTA plasma(n=5) 81-97 87
heparin plasma(n=5) 95-102 98


Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Apolipoprotein A1 (APOA1) were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Apolipoprotein A1 (APOA1) were tested on 3 different plates, 8 replicates in each plate.
CV(%) = SD/meanX100
Intra-Assay: CV<10%
Inter-Assay: CV<12%


The linearity of the kit was assayed by testing samples spiked with appropriate concentration of Apolipoprotein A1 (APOA1) 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) 83-97% 90-104% 97-105% 99-105%
EDTA plasma(n=5) 95-102% 80-93% 78-96% 98-105%
heparin plasma(n=5) 79-88% 81-103% 98-105% 89-97%


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.

CLIA Kit for Apolipoprotein A1 (APOA1)

Test principle

The microplate provided in this kit has been pre-coated with an antibody specific to Apolipoprotein A1 (APOA1). Standards or samples are then added to the appropriate microplate wells with a biotin-conjugated antibody specific to Apolipoprotein A1 (APOA1). Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. Then the mixture of substrate A and B is added to generate glow light emission kinetics. Upon plate development, the intensity of the emitted light is proportional to the Apolipoprotein A1 (APOA1) level in the sample or standard.;
