Description

This kit is based on Double antibody-Sandwich ELISA detection method and takes 5h assay time. The microplate provided in this kit has been precoated with anti IFN-gamma antibody. Add standard and properly diluted sample into relevant well respectively. After incubation, wash unbound components. Add biotinylated detection antibody. Then, it binds with IFN-gamma bound to precoated antibody. Add HRP-Streptavidin(HRP-SA) and Biotin system (BS). After incubation, wash unbound conjugate with wash buffer. TMB substrate is obtained by amplifying signal twice and used to visualize HRP enzymatic reaction. Wash unbound components and add TMB substrate solution. Then, TMB was catalyzed by HRP to produce a blue color product that turned yellow after adding a stop solution. Read the O.D. absorbance at 450nm in a microplate reader. Calculate the concentration of IFN-gamma in the sample by plotting standard curve. The concentration of the target substance is proportional to the OD450 value.

Recovery

Add a certain amount of IFN-gamma into the sample. Calculate the recovery by comparing the measured value with the expected amount of IFN-gamma in the sample.

Sample Type	Recovery Range(%)	Average(%)
serum(n=10)	90-103	99
EDTA plasma(n=10)	87-104	99
Heparin plasma(n=10)	87-105	95

Linearity

Dilute the sample with a certain amount of IFN-gamma at 1:2, 1:4 and 1:8 to get the recovery range.

Sample Type	1:2	1:4	1:8
serum(n=10)	90-105%	82-98%	82-92%
EDTA plasma(n=10)	86-105%	83-101%	84-92%
Heparin plasma(n=10)	88-99%	83-97%	83-96%

Specificity

Specifically binds with IFN-gamma , no obvious cross reaction with other analogues.

Standard Curve

This product is detected by QC department and meets performance required in the manual. (Laboratory Humidity: 20%-60%; Temperature: 18°C -25°C; Equilibrate TMB substrate to 37°C before staining. After adding into the ELISA wells, incubate for 15min at 37°C in dark.) Due to different assay environments and operations, assay data below and standard curve are provided for reference. Experimenters should establish standard curve according to their own assay.

Assay Procedure Summary

Step 1:
Take out the required plate wells, add 50ul Cap/Det Ab into each well, then add 50ul Standard or Sample into individual well. (When adding standard or sample, the disposable tip lightly touches the liquid level. Change the disposable tips for different samples and standards.) Gently tap the plate for 10s to ensure thorough mixing then static incubate for 60 minutes at 37°C.

Washing:
Wash the plate twice without immersion.

Step 2:
Add 100ul HRP-Streptavidin (orange) into each well, seal the plate and static incubate for 30 minutes at 37°C.

Washing:
Wash the plate five times without immersion.

Step 3:
Add 90ul TMB substrate solution, seal the plate and static incubate for 10-20 minutes at 37°C. (Accurate TMB visualization control is required.)

Step 4:
Add 50ul stop solution. Read at 450nm immediately and calculate.

Precision

Intra-assay Precision: samples with low, medium and high concentration are tested 20 times on the same plate.
Inter-assay Precision: samples with low, medium and high concentration are tested 20 times on three different plates.
