Notes on 025990J

Positive Control

Intended Use

The Positive Control is from a rabbit 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.

Characteristics

The positive control vial contains bovine IFNg in rabbit serum (lyophilized powder). Note: The mouse based serum used in this product are from healthy mouse of SPF standard (specific pathogen-free animals).

Expected Values

491.9pg/ml

Usage

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.

Assay Procedure Summary
