ELISA Kit for Anti-Collagen Type II Antibody (Anti-COL2)


This assay has high sensitivity and excellent specificity for detection of Anti-Collagen Type II Antibody (Anti-COL2).
No significant cross-reactivity or interference between Anti-Collagen Type II Antibody (Anti-COL2) and analogues was observed.


Matrices listed below were spiked with certain level of Anti-Collagen Type II Antibody (Anti-COL2) and the recovery rates were calculated by comparing the measured value to the expected amount of Anti-Collagen Type II Antibody (Anti-COL2) in samples.

Matrix Recovery range (%) Average(%)
serum(n=5) 79-93 84
EDTA plasma(n=5) 97-104 101
heparin plasma(n=5) 91-104 97


Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Anti-Collagen Type II Antibody (Anti-COL2) were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Anti-Collagen Type II Antibody (Anti-COL2) 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 Anti-Collagen Type II Antibody (Anti-COL2) 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) 82-95% 80-92% 98-105% 98-105%
EDTA plasma(n=5) 79-103% 98-105% 79-91% 91-99%
heparin plasma(n=5) 79-88% 78-99% 93-101% 94-102%


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.
