Notes on 026036J

Positive Control

Intended Use

The control vials are from a human serum sample known to contain IL1RA. It will provide a positive result in the ELISA assay, which indicates that the kit is optimized and working properly.


The control vial contains human IL1RA 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 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 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.

Storage and Stability

Store *026036A, *026036B, *026036D, *026036E and *026036J at -20?C. After reconstitution of *026036J, store at 4?C and use within 5 days. Store all the other components at 4?C. Unused kit is stable for 6 months after receipt. Once kit components are opened, it is highly recommended to use remaining reagents within 1 month provided this is within the expiration date of the kit. For maximum recovery of product, centrifuge the original vials after thawing and prior to removing the cap.
