Notes on 026500J

Positive Control

Intended Use

The control vials are 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.

Characteristics

The control vial contains rat LIF in rat serum (lyophilized powder). Note: The rat based serum used in this product is from a healthy specimen(s) of SPF standard (specific pathogen-free animals).

Expected Value

425.4pg/ml

Usage

Dissolve with 150ul standard diluent and let stand for 10min. 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.

Assay Procedure Summary
