Assay kits are widely used in many research areas including life science research, drug discovery, environmental monitoring, etc. They have become an indispensable tool in experiments. The existence of assay kits allows the experimenter to get rid of the heavy reagent preparation and optimization process. Because of that, researchers get more time to do further study.

Cusabio offers thousands of assay kits for researchers worldwide since 2007. These kits have most advantages of kits on the market, such as easy to use, time-efficient, wide application, etc. Moreover, CUSABIO provides 100% Risk-free Performance Guarantee so that the researchers don't need to worry about the product quality.

Over more than 14 years, CUSABIO Protein Expression Platform has established five recombinant expression systems from prokaryotic (E.coli) to eukaryotic (Yeast, mammalian cell and insect baculovirus), and has also built unique in vitro E.coli expression system, which enables us to express transmembrane proteins that are usually quite difficult to express. Furthermore, CUSABIO protein QC department owns a professional technical team, equipped with advanced experimental apparatus, to ensure each protein has a complete COA report and high quality. CUSABIO's purified proteins surpass 90% purity as detected by SDS-PAGE analysis.

CASUABIO currently have 67 native proteins, 100 small molecule antigens, 640 active proteins, 4400+ recombinant proteins in stock, 8900+ developed recombinant proteins, 13,000+ cDNA clones, 36,000+ transmembrane proteins, 500,000+ semi-customized recombinant proteins, and also could provide risk-free protein expression service and Gene, Oligo Synthesis service. All these products belong to their Protein Product Line.

Stable Cell Lines

Stable cell lines refer to cell lines that express a particular gene consistently and stably through stable transduction, or cell lines that interfere with the expression of a particular gene. Stable cell lines are crucial laboratory tools that can be used in many important applications, including the production of bio-therapeutic proteins, drug screening and gene function research. Specifically in the field of antibody development, stable cell lines can be used as immunogens to stimulate specific immune responses in animals, especially for targets of multiple transmembrane protein. In addition, stable cell lines are widely used in antibody binding and functional screening experiments.

Over more than 14 years, CUSABIO has rich experience in development of proteins and antibodies. Currently, CUSABIO has launched several stable cell lines of popular drug targets to fuel drug development.
