Specificity of the ELISA Kit for Collagen Type XVIII (COL18)

This assay has high sensitivity and excellent specificity for detection of Collagen Type XVIII (COL18).
No significant cross-reactivity or interference between Collagen Type XVIII (COL18) and analogues was observed.

Recovery of the ELISA Kit for Collagen Type XVIII (COL18)

Matrices listed below were spiked with certain level of recombinant Collagen Type XVIII (COL18) and the recovery rates were calculated by comparing the measured value to the expected amount of Collagen Type XVIII (COL18) in samples.

Matrix Recovery range (%) Average(%)
serum(n=5) 92-102 96
EDTA plasma(n=5) 87-101 95
heparin plasma(n=5) 97-105 101

Precision of the ELISA Kit for Collagen Type XVIII (COL18)

Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Collagen Type XVIII (COL18) were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Collagen Type XVIII (COL18) were tested on 3 different plates, 8 replicates in each plate.
CV(%) = SD/meanX100
Intra-Assay: CV<10%
Inter-Assay: CV<12%

Linearity of the ELISA Kit for Collagen Type XVIII (COL18)

The linearity of the kit was assayed by testing samples spiked with appropriate concentration of Collagen Type XVIII (COL18) 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) 85-101% 94-101% 90-104% 79-89%
EDTA plasma(n=5) 81-105% 82-93% 81-95% 81-95%
heparin plasma(n=5) 93-105% 86-101% 97-105% 92-101%

Stability of the ELISA Kit for Collagen Type XVIII (COL18)

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.

Test principle of the ELISA Kit for Collagen Type XVIII (COL18)

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 Collagen Type XVIII (COL18). Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Collagen Type XVIII (COL18). 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 Collagen Type XVIII (COL18), 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 Collagen Type XVIII (COL18) in the samples is then determined by comparing the O.D. of the samples to the standard curve.
