Invitrogen SureLock Tandem Midi Membranes and Filters, 0.2 μm, PVDF, have excellent binding properties for western blotting, dot-blot assays, and protein sequencing. The 0.2 μm pore size makes these membranes ideal for protein analysis of small amounts of protein (as little as 10 pmoles), amino acid analysis, and transfer of small molecular weight proteins and peptides. The dimensions (8.6 x 14 cm) of these PVDF membrane and filter paper sandwiches are ideal for wet-transfer of Invitrogen midi gels using the SureLock Tandem Midi Blot Module. The 0.2 μm pore size membrane and filter paper sandwiches are conveniently supplied as pack of 20.
