Specificity of the ELISA Kit for Gastric Intrinsic Factor (GIF)

This assay has high sensitivity and excellent specificity for detection of Gastric Intrinsic Factor (GIF).
No significant cross-reactivity or interference between Gastric Intrinsic Factor (GIF) and analogues was observed.

Recovery of the ELISA Kit for Gastric Intrinsic Factor (GIF)

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

Matrix Recovery range (%) Average(%)
serum(n=5) 99-105 102
EDTA plasma(n=5) 83-95 89
heparin plasma(n=5) 79-101 96

Precision of the ELISA Kit for Gastric Intrinsic Factor (GIF)

Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Gastric Intrinsic Factor (GIF) were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Gastric Intrinsic Factor (GIF) 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 Gastric Intrinsic Factor (GIF)

The linearity of the kit was assayed by testing samples spiked with appropriate concentration of Gastric Intrinsic Factor (GIF) 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) 85-99% 88-102% 96-103% 99-105%
EDTA plasma(n=5) 82-104% 87-94% 83-101% 82-95%
heparin plasma(n=5) 80-90% 87-105% 89-101% 91-99%

Stability of the ELISA Kit for Gastric Intrinsic Factor (GIF)

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 Gastric Intrinsic Factor (GIF)

This assay employs the competitive inhibition enzyme immunoassay technique. A monoclonal antibody specific to Gastric Intrinsic Factor (GIF) has been pre-coated onto a microplate. A competitive inhibition reaction is launched between biotin labeled Gastric Intrinsic Factor (GIF) and unlabeled Gastric Intrinsic Factor (GIF) (Standards or samples) with the pre-coated antibody specific to Gastric Intrinsic Factor (GIF). After incubation the unbound conjugate is washed off. Next, avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. The amount of bound HRP conjugate is reverse proportional to the concentration of Gastric Intrinsic Factor (GIF) in the sample. After addition of the substrate solution, the intensity of color developed is reverse proportional to the concentration of Gastric Intrinsic Factor (GIF) in the sample.
