PVDF/Filter Paper Sandwich, 0.2 μm, 8.3 x 7.3 cm (Invitrogen™)

PVDF/Filter Paper Sandwiches, 0.2 μm, have excellent binding properties for western blotting, dot-blot assays, and other protein or nucleic acid methods such as protein sequencing. The 0.2-μm pore size makes these membranes ideal for protein analysis of small amounts of proteins (as little as 10 pmoles), amino acid analysis, and transfer of small molecular weight proteins and peptides.
