Recovery

Matrices listed below were spiked with certain level of recombinant Cartilage Oligomeric Matrix Protein (COMP) and the recovery rates were calculated by comparing the measured value to the expected amount of Cartilage Oligomeric Matrix Protein (COMP) in samples.

Matrix Recovery range (%) Average(%)
serum(n=5) 84-101 93
EDTA plasma(n=5) 80-101 94
heparin plasma(n=5) 88-99 94

Precision

Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Cartilage Oligomeric Matrix Protein (COMP) were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Cartilage Oligomeric Matrix Protein (COMP) 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 Cartilage Oligomeric Matrix Protein (COMP) 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) 87-102% 93-105% 78-93% 78-94%
EDTA plasma(n=5) 91-103% 80-103% 81-96% 83-104%
heparin plasma(n=5) 98-105% 97-105% 93-101% 86-101%

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.

CLIA Kit for Cartilage Oligomeric Matrix Protein (COMP)

Test principle

The microtiter plate provided in this kit has been pre-coated with an antigen. Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated secondary antibody. 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 Cartilage Oligomeric Matrix Protein (COMP) level in the sample or standard.
