Precaution:The Stop Solution (027943K) included for use in this kit is an acid solution. Wear eye, hand, face, and clothing protection when using this material.
Storage and Stability:Store *027943A, *027943B, *027943D, *027943E and *027943J at -20°C. After reconstitution of *027943J, 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.
Notes on 027943J Positive Control:Intended Use:The positive control is from 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.
Characteristics:The positive control vial contains human S100A9 in human serum (lyophilized powder). Note: The human based material used in this product is screened for HIV, Hepatitis A, B, C, HTLV and Syphilis.
Expected Values:217.1pg/ml
Usage:Disslove with 150ul standard dilutent 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 your specimens. Note: After reconstitution, store Positive Control vial at 4°C and use within 5 days.
