Blotting membranes & papers

A blotting membrane, nitrocellulose or PVDF, binds proteins transferred out of a gel. Pore size, 0.2 µm or 0.45 µm, and the format, roll or pre-cut, are the choices. PVDF is activated in methanol. The papers and the sponges around it in the cassette are part of the same stack.

Protein work separates a mixture, then asks which protein is which. Extraction and purification take the protein out of the cell. A marker shows the masses. A Western blot moves the separated proteins onto a membrane and probes them with an antibody. The membrane, nitrocellulose or PVDF, has to bind the protein and survive the washes. Antibodies and methods are in PubMed. Reference material is at ATCC.
