Notes on 023686J

Positive Control

Intended Use

The Positive Control is from is from a 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 positive control vial contains rat bCTxI in rat serum (lyophilized powder). Note: The rat source material used in this product are from healthy animal of SPF standard (specific pathogen-free animals).

Expected Values



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.
