Recovery

Matrices listed below were spiked with certain level of recombinant Interferon Alpha 21 (IFNa21) and the recovery rates were calculated by comparing the measured value to the expected amount of Interferon Alpha 21 (IFNa21) in samples.

Matrix	Recovery range (%)	Average(%)
serum(n=5)	80-91	84
EDTA plasma(n=5)	79-96	83
heparin plasma(n=5)	78-101	83

Linearity

The linearity of the kit was assayed by testing samples spiked with appropriate concentration of Interferon Alpha 21 (IFNa21) 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)	78-94%	81-104%	84-96%	81-92%
EDTA plasma(n=5)	78-104%	80-89%	93-101%	84-92%
heparin plasma(n=5)	95-102%	89-98%	90-104%	96-105%

Features

Detects protein (regular version)

Species

Human

Precautions

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.

Precision

Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Interferon Alpha 21 (IFNa21) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Interferon Alpha 21 (IFNa21) were tested on 3 different plates, 8 replicates in each plate.
CV(%) = SD/meanX100
Intra-Assay: C<10%
Inter-Assay: C<12%

Notes

The microplate provided in this kit has been pre-coated with an antibody specific to Interferon Alpha 21 (IFNa21). Standards or samples are then added to the appropriate microplate wells with a biotin-conjugated antibody specific to Interferon Alpha 21 (IFNa21). 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 Interferon Alpha 21 (IFNa21) level in the sample or standard.;

Usage Notes

1. Prepare all reagents, samples and standards;
2. Add 100µL standard or sample to each well. Incubate 1 hours at 37°C;
3. Aspirate and add 100µL prepared Detection Reagent A. Incubate 1 hour at 37°C;
4. Aspirate and wash 3 times;
5. Add 100µL prepared Detection Reagent B. Incubate 30 minutes at 37°C;
6. Aspirate and wash 5 times;
7. Add 100µL Substrate Solution. Incubate 10 minutes at 37°C;
8. Read RLU value immediately.
