Recovery

Matrices listed below were spiked with certain level of recombinant Phospholipase A2, Lipoprotein Associated (LpPLA2) and the recovery rates were calculated by comparing the measured value to the expected amount of Phospholipase A2, Lipoprotein Associated (LpPLA2) in samples.

Matrix Recovery range (%) Average(%)
serum(n=5) 96-105 101
EDTA plasma(n=5) 78-104 91
heparin plasma(n=5) 85-96 91

Precision

Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Phospholipase A2, Lipoprotein Associated (LpPLA2) were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Phospholipase A2, Lipoprotein Associated (LpPLA2) 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 Phospholipase A2, Lipoprotein Associated (LpPLA2) 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) 82-91% 89-99% 83-98% 96-104%
EDTA plasma(n=5) 98-105% 89-97% 78-101% 78-94%
heparin plasma(n=5) 78-95% 83-97% 78-102% 94-101%

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 Phospholipase A2, Lipoprotein Associated (LpPLA2)

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 Phospholipase A2, Lipoprotein Associated (LpPLA2). Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Phospholipase A2, Lipoprotein Associated (LpPLA2). 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 Phospholipase A2, Lipoprotein Associated (LpPLA2), 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 Phospholipase A2, Lipoprotein Associated (LpPLA2) in the samples is then determined by comparing the O.D. of the samples to the standard curve.
