Mission/Background :
Our core competence is protein production technology, we are engaged in protein production, production of antigens and antibodies, development of interaction tools.
Since its establishment, we succeeded in developing various reagents and kits based on these basic technologies. In recent years, we have developed an affinity ligand for antibody purification (low molecular weight) (patent pending) and succeeded in commercialization of purification carrier using this.
Furthermore, by introducing external technology, we have developed a system that can conduct screening services for small molecule antibodies such as VHH antibodies and are considering advancing into diagnostic measurement fields utilizing this technology.

Technology & Business
We have a variety of expression systems such as Brevibacillus bacteria, Escherichia coli and other microorganisms, animal cells, cell-free translation system and so on, we can respond to customer's demand to the maximum, we can cope with various kinds of chromatography.
We also commercialized resins and affinity magnetic beads that immobilized affinity ligands (patent pending) for antibody purification (low molecular weight) developed using these basic technologies, and became products with excellent cost performance compared with conventional products We will.
Others Our VHH antibody screening and production service is a method that enables us to obtain antibodies without using laboratory animals and it is also an effective service for producing antibodies against antigens that could not be acquired by conventional methods We are.
