Description
Blotting paper Grade BF 4, provided as 150 × 150 mm sheets, is a high-purity paper grade suited to blotting and chromatography and to applications in which strong, uniform absorption is important. Square sheets of this size are convenient for mid-format gel transfers, membrane stacks, and diagnostic or life-science procedures that rely on predictable wicking and liquid uptake. The material supports clean sample handling and can be layered or trimmed to match common blot and filter layouts. Packs of 25 sheets from manufacturer Sartorius offer a practical stock unit for research and routine laboratory work. The grade is non-sterile and serves equally well as filter sheet stock, protective underlay, or absorbent bench cover where cellulose media are preferred. High purity contributes to low background in blotting and chromatographic separations, while the 150 × 150 mm format balances coverage with economical use of material. Laboratories can deploy these sheets across analytical, diagnostic, and protective tasks that depend on reliable absorbency.

Questions about Blotting papers/ Grade BF 4
What is this article?
Blotting papers/ Grade BF 4 is the article on this page. Luminix Health distributes Sartorius for laboratory use. It sits in Blotting membranes & papers, inside Protein biology & Western blot, in Microbiology lab supplies.
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.
