Nitrocellulose Membrane For Lateral Flow Test

Nitrocellulose Membrane

Nitrocellulose membrane (NC membrane) is the core carrier of the colloidal gold test and the most important consumable in immunoassays. Through continuous optimization of surface chemical composition and unique production process, BSK BasicAR NC membrane shows high intra- and inter-lot consistency. Now our membranes are widely used in immunodiagnosis, agriculture, food and environmental science, etc.
