What Is In Vitro Display Technology?

Fig.1 Experiment (Creative Biolabs AI) In vitro display technology is a cutting-edge cell-free genotype-phenotype coupling screening technology. It fundamentally breaks the inherent limitations of traditional in vivo cell display systems based on bacteria and yeast. All protein and polypeptide expression, display, panning and enrichment procedures are performed in a controlled ex vivo system.

The core principle is precise coupling of molecular functional phenotypes with nucleic acid genotypes. Through multiple rounds of gradient pressure screening, high-specificity, high-affinity and high-stability target molecules are rapidly enriched from ultra-large mutation libraries. It constitutes the fundamental upstream core technology supporting the research and development of antibody therapeutics, peptide pharmaceuticals and raw materials for in vitro diagnostics.

Creative Biolabs boast years of experience in in vitro display technologies with a mature one-stop screening R&D platform. Feel free to discuss all your research inquiries with scientists

Four Differentiated In Vitro Display Systems
