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.
Mature technology with high-cost performance. Suitable for conventional antibody and polypeptide screening, serving as the preferred general solution for innovative drug and diagnostic raw material development.
Eukaryotic expression system with quantitative sorting. Featuring post-translational modifications and correct protein folding, it is the premier choice for multi-parameter FACS-based screening, specific epitope targeting, and precise affinity maturation of human antibodies.
Host-free restriction and ultra-large library capacity. Ideal for high-complexity mutation library screening and in-depth affinity maturation of target molecules.
Ultra-high screening precision with low background noise. Optimized for high-specificity, low off-target screening and fine-grained draggability optimization.
