Specificity of the ELISA Kit for Complement Component 3 (C3)

This assay has high sensitivity and excellent specificity for detection of Complement Component 3 (C3).
No significant cross-reactivity or interference between Complement Component 3 (C3) and analogues was observed.

Recovery of the ELISA Kit for Complement Component 3 (C3)

Matrices listed below were spiked with certain level of recombinant Complement Component 3 (C3) and the recovery rates were calculated by comparing the measured value to the expected amount of Complement Component 3 (C3) in samples.

Matrix Recovery range (%) Average(%)
serum(n=5) 83-95 91
EDTA plasma(n=5) 95-104 98
heparin plasma(n=5) 98-105 102

Precision of the ELISA Kit for Complement Component 3 (C3)

Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Complement Component 3 (C3) were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Complement Component 3 (C3) 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 Complement Component 3 (C3)

The linearity of the kit was assayed by testing samples spiked with appropriate concentration of Complement Component 3 (C3) 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) 98-105% 79-104% 90-98% 88-101%
EDTA plasma(n=5) 80-101% 95-105% 94-101% 90-104%
heparin plasma(n=5) 83-101% 78-101% 97-105% 98-105%

Stability of the ELISA Kit for Complement Component 3 (C3)

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 Complement Component 3 (C3)

This assay employs the competitive inhibition enzyme immunoassay technique. A monoclonal antibody specific to Complement Component 3 (C3) has been pre-coated onto a microplate. A competitive inhibition reaction is launched between biotin labeled Complement Component 3 (C3) and unlabeled Complement Component 3 (C3) (Standards or samples) with the pre-coated antibody specific to Complement Component 3 (C3). 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 Complement Component 3 (C3) in the sample. After addition of the substrate solution, the intensity of color developed is reverse proportional to the concentration of Complement Component 3 (C3) in the sample.
