Invitrolon™ PVDF/Filter Paper Sandwiches are pre-cut and pre-assembled—ready for protein blotting/transfer. While our 0.2 µm PVDF membrane performs well for protein transfer, Invitrolon™ PVDF is a high-quality, 0.45 µm PVDF membrane, particularly suitable for high-sensitivity and low-background immunoblotting.

Membranes are pre-cut to 8.3 cm x 7.3 cm to fit mini-gels and pre-assembled with two filter papers to simplify blotting setup. In addition, Invitrolon™ PVDF offers:

Uniform 0.45 µm pore size—ideal for Western transfer of proteins >10 kDa

High binding capacity—to enhance sensitivity and reduce background (see figure)

Reprobing characteristics—to eliminate repeat runs and transfers

Durability and solvent-resistance—for protein sequencing and amino acid analysis
