Company Overview

Clinical testing determines patients’ physical condition: whether they have any diseases, and, if so, the progress of the disease, thereby providing essential data by which hospitals can decide upon a treatment plan. Testing samples of blood, urine, and cells (diagnostic testing) in particular, provides a variety of useful information and is often performed at many different institutions for various purposes. Sysmex is a comprehensive supplier of instruments, reagents, and software necessary for diagnostic testing. By integrating R&D, production, sales, and after-sales support, we provide hospitals and commercial laboratories with quality products and support.

ProCube ‐ Our History ‐
Sysmex acquired protein expression technology from Katakura Industries Co., Ltd., Research Institute of Biological Science, to provide a stable supply of protein for non-hematology reagents. To reduce lot variability and contamination risk for workers, Sysmex developed a diagnostic reagent using recombinant protein produced in silkworm-baculovirus expression system. To meet a growing demand from the pharmaceutical industry, Sysmex started a protein production service for drug research and development. ProCube recombinant protein production service was established in October, 2011. ProCube’s flexibility allows for a broad range of customer relationships, delivering customized solutions via direct sales, partnerships and collaborations.
