What C. difficile antibodies does List Labs have that can be used in a sandwich assay?

Last Updated: Aug 30, 2018 01:24PM PDT
Thank you for your interest in List Labs.

Goat antisera to C. difficile Toxin A (List Labs product #752) can be paired with the chicken anti-C. difficile Toxin A antibodies (List Labs product #753), the latter used as the capture antibody, to detect low levels of the Toxin A antigen (List Labs product #152).

For example, a 1 µg coating of product #753 followed by exposure to the antigen and a 1: 1,000 dilution of the goat antisera gives a midpoint of approximately 40 ng/ml. As low as 1 ng/ml of antigen is readily detected using a standard chromogenic substrate. 

You may view the Certificate of Analysis (COA) for these products on our website for more details.​
