With the rise of China's biological industry and the application of biological products, high purity of biologically active protein are in increasing demand. Here in Realgene, we use sophisticated biological expression systems and technology that includes a large fermentation tank, bioreactor, and mass-based purification systems to provide proteins in gram quantities with up to 98% purity to meet large-scale protein expression needs of the customers. So far we have many satisfied customers internationally that have benefitted tremendously from our large-scale protein preparation services.
