To all scientific research users: The MiaoLing Plasmid Platform was initiated by Miaoling Biotech and participated by industry scholars. It is a resource-sharing platform built based on the early achievements of its own scientific research in aspects such as plasmid stability, strain preservation activity, and strain resistance characteristics. We are equipped with professional instruments and equipment such as -80℃ ultra-low temperature refrigerators, super clean workbenches, autoclaves, and high-speed large centrifuges. At the same time, we have many staff members who have been engaged in molecular biology research for a long time. We can quickly and effectively help global biological researchers share and obtain plasmids. This platform is open and compatible, gathering plasmid vector strain resources that can be publicly disclosed and exchanged by scientific researchers. After purification, validation, proper preservation and regular calibration, a mature platform system has been formed and is open to a wide range of users. We hope to enhance the communication of scientific research information through the collection, screening, transformation, exchange and transmission of the platform, promote cooperation in the domestic scientific research field, and contribute to the biological scientific research in China.
