# GenScript Biotech

> GenScript Biotech is a global biotechnology company headquartered in Piscataway, New Jersey, with major operations in Nanjing, China, that provides gene synthesis, peptide synthesis, antibody engineering, protein expression, and cell-based assay services to academic and pharmaceutical researchers worldwide. Founded in 2002, GenScript quickly became the world's largest gene synthesis company by offering turnaround times and pricing that democratized access to synthetic genes for labs of all sizes. Their OptimumGene codon optimization algorithm and GenSmart optimization tool enable researchers to maximize protein expression in chosen host systems. GenScript produces recombinant proteins, including challenging membrane proteins and antibody fragments, through baculovirus, E. coli, yeast, and mammalian expression systems. Their MonoRab and OmniRab rabbit monoclonal antibody platforms generate highly specific recombinant antibody leads for therapeutic and research applications. GenScript's CRISPR cell line engineering services, including knockout, knock-in, and endogenous tagging projects, support cell biology and drug target validation research. The company's ProSci peptide chemistry capabilities support custom synthesis of phosphopeptides, stapled peptides, and other modified sequences for research and immunization. Their cell therapy enabling services business unit provides contract manufacturing support for CAR-T and other cell therapies. GenScript subsidiary Bestzyme offers industrial enzyme solutions, and Legend Biotech is their publicly traded CAR-T therapy development company.
