These positively charged membranes provides higher sensitivities and rapid nucleic acid binding without the need for UV crosslinking or baking. The surface chemistry is characterized by a high density of strongly cationic quaternary ammonium groups which are an integral part of the membrane. TotalBLOT+™ Nylon Membranes are ideal for superior binding of negatively charged biomolecules in a wide variety of nucleic acid and protein applications. Available sizes: 10 x 10 cm or 30 cm x 3 m (1 roll).
