Merck offers four different PVDF membranes, each optimized for different protein blotting applications. We also now offer blotting sandwiches that feature pre-cut sheets of membrane and blotting filter paper.
Immobilon® PVDF Membrane Advantages Compared to Nitrocellulose
Won’t crack or curl, and they can be cut without fracturing.
Broad solvent compatibility
Superior staining capabilities
Can be reprobed multiple times
Compatible with a variety of detection chemistries, including radioactive, chromogenic, chemiluminescent, fluorescent, and chemifluorescent techniques
Immobilon® PVDF membranes offer excellent protein binding and high signal.
Immobilon® PVDF membranes have high protein adsorption, so you won’t lose proteins during transfer or reprobing. The open pore structure makes it easy to access bound proteins and remove unbound probes. In addition, Immobilon® PVDF membranes optimized for fluorescent blots dramatically increase signal for high sensitivity in quantitative, multiplexing applications.
Immobilon®-Eis the only PVDF membrane (0.45µm) that wets out in aqueous buffers, eliminating the methanol pre-wet step. This membrane is well-suited for most Western blotting applications.
Immobilon®-Pmembrane (0.45 µm) is a versatile substrate that is well-suited for common immunoblotting applications.
Immobilon®-PSQmembrane (0.2 µm) is ideal for protein sequencing and immunoblotting of low molecular weight proteins. It has a higher protein binding capacity and a higher retention than 0. 45 µm membranes.
Immobilon®-FL membrane (0.45 µm) was developed for fluorescence-based immunodetection. It has very low background fluorescence across a wide range of excitation and emission wavelengths.
