Storage and Stability

Store *028248A, *028248B, *028248D, *028248E and *028248J at -20?C. After reconstitution of *028248J, store at 4?C and use within 5 days. Store all the other components at 4?C. Unused kit is stable for 6 months after receipt. Once kit components are opened, it is highly recommended to use remaining reagents within 1 month provided this is within the expiration date of the kit. For maximum recovery of product, centrifuge the original vials after thawing and prior to removing the cap.

Notes on 028248J

Positive Control

Intended Use

The control vials are from mouse serum sample known to contain the target protein. It will provide a positive result in the ELISA assay, which indicates that the kit is optimized and working properly.


The control vials contain mouse SPD in mouse serum (lyophilized powder). Note: The mouse based material used in this product is from healthy mice of SPF standard (specific pathogen-free animals).

Expected Values

The concentration of the control was determined by subtracting two standard deviations to the mean optical density value of twenty QC sample replicates and calculating the corresponding concentration.


Disslove with 150ul standard dilutent and let stand for 10 minutes. Mix gently before use. In the experiment, add 100ul to an appropriate well of the plate and test its concentration along with standards and your specimens. Note: After reconstitution, store Positive Control vial at 4?C and use within 5 days.

Assay Procedure Summary

1. Prepare all reagents, samples and standards;
2. Add 100ul standard or sample to each well. Incubate 1 hour at 37?C.
3. Aspirate and add 100ul prepared Detection Reagent A. Incubate 1 hour at 37?C.
4. Aspirate and wash 3 times.
5. Add 100ul prepared Detection Reagent B. Incubate 30 minutes at 37?C.
6. Aspirate and wash 5 times.
7. Add 90ul TMB Substrate. Incubate 10-20 minutes at 37?C.
8. Add 50ul Stop Solution. Read at 450nm immediately.
