SYSTEM FOR DETERMING UNPROCESSED AND PARTIALLY PROCESSED NEUROTOXIN TYPE A

摘要

The present invention is concerned with tools for the quality control and safety during manufacture of neurotoxins. In particular, it relates to a method for the determination of the amount of partially processed and/or unprocessed Botulinum neurotoxin A polypeptide (BoNT/A) in a solution comprising processed and partially processed and/or unprocessed BoNT/A comprising the steps of contacting a sample of said solution with a capture antibody which specifically binds to the partially processed and unprocessed BoNT/A under conditions which allow for binding of said antibody to said partially processed and unprocessed BoNT/A, whereby a complex is formed, and determining the amount of the formed complex, whereby the amount of the complex is indicative for the amount of the partially processed and/or unprocessed BoNT/A in said solution. Moreover, the present invention contemplates a device and a kit for carrying out said method.
