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

Notes on 023775J

Positive Control

Intended Use

The control vial is from a porcine serum sample known to contain BNP. It will provide a positive result in the ELISA assay, which indicates that the kit is optimized and working properly.


The control vial contains porcine BNP in porcine serum (lyophilized powder). Note: The porcine source material used in this product is from healthy porcine of SPF standards (specific pathogen-free animals).

Expected Values



Dissolve with 150ul standard diluent and let it stand for 10 minutes. If powder is partly insoluble, shake gently until fully dissolved. 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: 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
