Notes on 023553J

Positive Control

Intended Use

The positive control is from a human sample known to contain the AQP2. 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 human AQP2 (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 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.
