Storage and Stability

Store *024124A, *024124B, *024124D, *024124E and *024124J at -20?C. After reconstitution of *024124J, 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 024124J

Positive Control

Intended Use

The control vial is from a rat tissue homogenates sample known to contain CTGF. It will provide a positive result in the ELISA assay, which indicates that the kit is optimized and working properly.


The control vial contains rat CTGF in rat tissue homogenates (lyophilized powder). Note: The rat source material used in this product is from healthy rat of SPF standards (specific pathogen-free animals).

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.

Assay Procedure Summary
