Storage and Stability

Store *023757A, *023757B, *023757D, *023757E and *023757J at -20?C. After reconstitution of *023757J, 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 023757J

Positive Control

Intended Use

The positive control is from a 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 positive control vial contains BSA in serum (lyophilized powder). Note: The human based material used in this product is screened for HIV, Hepatitis A, B, C, HTLV and Syphilis.

Expected Values



Dissolve with 150ul standard diluent and let stand for 10 minutes. If powder is partly insoluble, shake gently until fully dissolved. Mix gently before use. In the experiment, add 50ul to an appropriate well of the plate and test its concentration along with standards and your specimens. Note: Upon receipt store Positive Control vial at -20?C. 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 50ul standard or sample to each well, then add 50ul Detection Reagent A immediately. Shake and mix. Incubate 1 hour at 37?C.
3. Aspirate and wash 3 times.
4. Add 100ul prepared Detection Reagent B. Incubate 30 minutes at 37?C.
5. Aspirate and wash 5 times.
6. Add 90ul Substrate Solution. Incubate 10-20 minutes at 37?C.
7. Add 50ul Stop Solution. Read absorbance at 450nm immediately.
