Abstrakt: Monoclonal antibodies (mAbs) targeting bacterial virulence factors may represent promising therapeutics in the fight against severe bacterial infections. Here, we present an approach for developing human-derived antibodies targeting the type III secretion system (T3SS) of Pseudomonas aeruginosa (PA) by neutralizing the function of the T3SS-tip protein PcrV. The protocol involves identifying individuals with protective antibodies, isolating PcrV-specific B cells from these individuals, and producing and testing anti-PcrV mAbs derived from single B cells. For complete details on the use and execution of this protocol, please refer to Simonis et al. 1 .
Competing Interests: Declaration of interests A patent application for a set of highly neutralizing antibodies developed using the described workflow has been filed by the University of Cologne, with A.S., C.K., F.K., and J.R. listed as inventors.
