Notes on 023755J

Positive Control

Intended Use

The control vial is from a human serum sample known to contain BSP. 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 BSP in humanserum (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 diluent and let it 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.
