Positive Control

Intended Use

The control vials are from a human 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 vials contain human a1AT in human serum (lyophilized powder). Note: The human based serum used in this product are screened for HIV, Hepatitis A, B, C, HTLV and Syphilis.

Expected Value



Dissolve with 150ul standard diluent and let stand for 10 minutes. Mix gently before use. In the experiment, add 100ul to an appropriate well of the plate and test its concentration along with standards and samples. Note: Upon receipt store Positive Control vial at -20?C. After reconstitution, store Positive Control vial at 4?C and use within 5 days.
