Southern Blotting: a Brief Overview - The Official Blog of Edvotek Since the nitrocellulose membrane used in lateral flow assays adsorbs proteins well and typically has a negative surface charge similar to an ELISA plate, there is a potential for the optical label or for the intermediary linker (detecting antibody, binder, or aptamer) to bind nonspecifically to the membrane (Holstein, 2015). The low-nitrogen form of nitrocellulose is soluble in .
