Magic™ Anti-C. difficile Toxin A polyclonal antibody (CABT-B1970)

Chicken Anti-C. difficile Toxin A polyclonal antibody for WB, ELISA, sELISA


Host Species
Antibody Isotype
Species Reactivity
C. difficile
Toxin A from Clostridium difficile


Application Notes
WB: A dilution 1:2000 of the antibody was an effective probe for 0.5 μg of C. difficile Toxin A subunit.
Direct ELISA: The antibody titer, measured at the midpoint, was 1:23000 using a 2 ug coating of C. difficile Toxin, A subunit.
We recommend the following for sandwich ELISA (Capture - Detection):
CABT-B1970 - CABT-B1084
For example, a 1 μg coating of CABT-B1970 fllowed by exposure to the antigen and a 1:1000 dilution of the goating 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.
*Suggested working dilutions are given as a guide only. It is recommended that the user titrates the product for use in their own experiment using appropriate negative and positive controls.


Alternative Names
