Recovery

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

Matrix Recovery range (%) Average(%)
serum(n=5) 93-101 96
EDTA plasma(n=5) 96-105 101
heparin plasma(n=5) 94-102 97

Precision

Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Glucokinase (GCK) were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Glucokinase (GCK) 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 Glucokinase (GCK) 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) 80-104% 95-103% 94-101% 96-104%
EDTA plasma(n=5) 99-105% 87-101% 92-105% 93-101%
heparin plasma(n=5) 89-101% 78-98% 83-95% 93-101%

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 Glucokinase (GCK)

Test principle

The microplate provided in this kit has been pre-coated with an antibody specific to Glucokinase (GCK). Standards or samples are then added to the appropriate microplate wells with a biotin-conjugated antibody specific to Glucokinase (GCK). 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 Glucokinase (GCK) level in the sample or standard.;
