Large-scale protein preparation

With the rise of China's biological industry and the increasing use of biological products, the demand for high-purity active proteins is increasing. Shanghai Ruiji Bio has mature expression system and the most advanced protein expression technology, and has a large fermentation tank, bioreactor, large-scale purification system, etc., can provide grams of active protein with a purity of up to 98%, fully satisfied Customer needs for large-scale protein expression. We have successfully expressed more than 10 proteins for customers on a large scale, and purified the active proteins with purity grade and quantity required by customers.
