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.
