Proteins & Protein Expression

Cosmo Bio USA offers a comprehensive and expertly curated Proteins & Protein Expression portfolio, supporting a wide range of research in molecular biology, proteomics, immunology, regenerative medicine, and synthetic biology. Cosmo Bio Co., Ltd. supplies a broad selection of recombinant proteins—cytokines, growth factors, enzymes, and fusion-tagged proteins—for functional assays, signaling studies, and protein–protein interaction analysis. CUSABIO adds a vast catalog of recombinant proteins validated for high-impact targets in cancer, immunology, neuroscience, and infectious disease, enabling reliable performance in both biochemical and cell-based assays. CUSAg enhances assay development with specialized recombinant proteins and small molecule–protein conjugates, ideal for sensitive detection in food safety and contaminant screening applications.

Cellular Engineering Technologies (CET) advances the offering with yeast-derived, xeno-free human growth factors such as M-CSF and RANKL—tailored for iPSC maintenance and osteoclast differentiation under defined, animal-free conditions. MBL International delivers essential immunology proteins, including MHC monomers and tetramers for antigen-specific T cell detection and vaccine research. Atlas Antibodies supports antibody validation and assay standardization with its recombinant PrEST antigens. Home Algae Biotechnology introduces algae-derived fluorescent proteins for sustainable, innovative bioimaging and biosensor applications. GSK completes the portfolio with the PUREfrex® system, a high-fidelity, cell-free protein synthesis platform ideal for precise protein expression, synthetic biology, and minimal cell system construction. Together, these rigorously validated tools position Cosmo Bio USA as a trusted provider of efficient, scalable, and application-specific protein research solutions across the life sciences.
