Build DNA variant libraries on demand, in your lab with the BioXp™ system - an automated synthetic biology workstation for building gene fragments, clones, and libraries.
BioXp™ variant libraries application note
DNA variant libraries are a powerful tool for manipulating protein structure for optimization studies in discovery biology, protein engineering, and several other disciplines. In this application note, we worked with a customer to build high-quality DNA variant libraries with the BioXp™ system, the world’s only full-stack synthetic biology workstation for on-demand DNA assembly and amplification. The customer generated data for two library builds, completing the projects in five days, where using traditional service providers would have taken two weeks to one month — a significant time savings during the design, build, test cycle.
Improvements in target validation rates by automating and streamlining antibody production
Case study: Adopting the BioXp™ system compresses design-build-test cycle times and increases pipeline by 25% for one biopharmaceutical company developing an antibody-based therapeutic
Engineered T cells have been used successfully to treat several leukemias and solid tumors. However, building and screening engineered T cell receptors is time-consuming and labor-intensive. Learn how a biopharmaceutical company transitioned from a traditional method of building expression constructs for chimeric antigen receptors (CAR) to an automated method using the BioXp™ system. The BioXp™ system is the world’s first and only commercially available push-button automated platform for on-demand synthesis of DNA fragments, libraries, and more. The traditional method relied on manual processes for DNA fragment synthesis, cloning, and tracking the reactions. The large number of candidates required for screening made this method prone to human error, cumbersome, and complicated. Adopting the BioXp™ system streamlined the building of expression constructs, eliminating several manual processes from the workflow, and accelerated the identification of lead candidates.
