For maximum recovery of product, centrifuge the original vials after thawing and prior to removing the cap.

Notes on 024470J

Positive Control

Intended Use

The positive control is from rat 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 vial contains rat CTX11 in rat serum (lyophilized powder).
Note: The mouse based serum used in this product are from healthy mouse of SPF standard (Specific Pathogen-Free animals).

Expected Value



Dissolve with 150ul standard dilutent 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 prepared 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 at 450nm immediately.
