The quality of in vitro diagnostic products is largely determined by the upstream core raw materials. Antigens and antibodies, enzymes and coenzymes are important components that contribute to the diagnostic function of in vitro diagnostic reagents, affecting their performance levels such as sensitivity and stability. Reaction carriers such as NC membranes, ELISA plates and magnetic beads, provide a site for biochemical reaction, ensuring stable and smooth diagnostic reactions.


The lateral flow test strips for in vitro diagnosis mainly consists of four parts: sample pad, binding pad, reaction membrane (Nitrocellulose), and absorbent pad. Cobetter self-developed and produced nitrocellulose membrane NC140C and NC95C, meet the production requirements of diagnostic lateral test manufacturers.
