Description

This kit is based on Competitive-ELISA detection method and takes 2h assay time. The microplate provided in this kit has been precoated with PGI2. PGI2 in the sample or standard competes with a fixed amount of biotin-labeled PGI2 for sites on a pre-coated antibody specific to PGI2. Free components are washed off. After adding HRP-Streptavidin Conjugate (SABC), biotin specifically binds with streptavidin to form immune complexes. Wash off unbound conjugate. Add TMB substrate solution. Then, TMB was catalyzed by HRP to produce a blue color product that tued yellow after adding a stop solution. Read the O.D. absorbance at 450nm in a microplate reader. Compare OD450 value of sample with the standard curve through curve fitting software to determine the concentration of PGI2 in the sample. The concentration of the target substance is inversely proportional to the OD450 value.

Recovery

Add a certain amount of PGI2 into the sample. Calculate the recovery by comparing the measured value with the expected amount of PGI2 in the sample.

Sample Type	Recovery Range(%)	Average(%)
serum(n=10)	90-98	94
EDTA plasma(n=10)	87-104	93
Heparin plasma(n=10)	89-100	95

Linearity

Dilute the sample with a certain amount of PGI2 at 1:2, 1:4 and 1:8 to get the recovery range.

Sample Type	1:2	1:4	1:8
serum(n=10)	86-96%	86-99%	85-99%
EDTA plasma(n=10)	85-104%	86-98%	88-100%
Heparin plasma(n=10)	86-103%	88-98%	88-97%

Specificity

Specifically binds with PGI2 , 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:
Wash the plate twice before adding the standard and sample.

Step 2:
Add 50ul standard or sample into each well. Immediately add 50ul biotin-labeled antibody working solution into each well(The tip can't be reused after touching the liquid.), gently shake the plate for 1min, seal closely and statically incubate for 45 minutes at 37°C.

Washing:
Wash the plate three times and immerse for 1min each time.

Step 3:
Add 100ul HRP-Streptavidin Conjugate (SABC) working solution into each well, seal the plate and statically incubate for 30 minutes at 37°C.

Washing:
Wash the plate five times and immerse for 1min each time.

Step 4:
Add 90ul TMB substrate solution, seal the plate and statically incubate for 10-20 minutes at 37°C. (Accurate TMB visualization control is required.)

Step 5:
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.

Usage Notes

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.
