Profile: Xiamen Sunma Biotechnology Co., Ltd. develops life science products. We are specialized in developing agarose, agarose gel, agarose precast gel, transfection reagent and selective antibotics. Sofast® gene transfection reagent is a cationic polymer gene transfection reagent. It has several unique features necessary for efficient transfection, such as DNA condensation and endosomal release, which can improve gene transfection efficiency. Compared with cationic lipids, cationic polymers are very stable, easy to handle and more resistant to serum in cell culture. Sofast® is widely used for both primary cell and established cell lines. Agarose is a neutral polysaccharide extracted from certain seaweeds. The molecular structure of this polysaccharide gives the capacity to form gels that are strong even at low concentrations.
