Technology Platform

There are many challenges our clients face every day: low bioactivity; batch-to-batch inconsistency; poor immunogenicity; soluble transmembrane antigens; etc. In response to these unmet needs, KactusBio has established a unique and innovative functional recombinant protein production platform called Structure Aided design and Multiplex Screening (SAMS).
We apply both bioinformatics and computer simulations to design the protein to the specifications of the client's application. Multiple constructs to the same protein are made at once and combined with our proprietary multiplexing screening technology, we can obtain the optimal expression clone in the shortest time.
