Introducing the H5 category work titled '3V Cys-C Kit Reference'. This work showcases the journey of the first customer of our company's Cys-C kit, which was Air Industry Xiangyang Hospital, a second-grade level A comprehensive hospital. The Cys-C kit, like other specific protein kits from our company, underwent rigorous evaluation before entering the market. The evaluation included full performance type testing, clinical trials, reference substance traceability experiments, 37℃ thermal stability tests, freezing tests, and vacuum tests to ensure its effectiveness under extreme conditions. This work was created using Eqxiu's 'online design' platform, which offers a rich variety of templates for quick and easy creation. The use of Eqxiu's online design platform is highlighted as a key aspect of this work.
