Description
Blotting paper Grade BF 4 in 110 × 170 mm sheets is a high-purity paper grade developed for blotting and chromatography and for other uses where the absorption behaviour of the paper is critical. The compact sheet size suits mini-gel transfers, small blot assemblies, and diagnostic or life-science protocols that need controlled wicking without excess material waste. Consistent absorbency supports reliable sample movement and liquid distribution across membranes and gels. This grade is supplied by manufacturer Sartorius in packs of 25 sheets, giving laboratories a convenient unit for method development and routine runs. Non-sterile sheets can be cut or stacked as needed for filter layers, protective pads, or bench underlays. The format fits standard small-format electrophoresis and blotting workflows while remaining useful as general absorbent cover paper in clean laboratory areas. High purity helps limit unwanted background in sensitive blotting and chromatographic steps, making Grade BF 4 a practical choice for diagnostics, life science, and everyday absorbent-paper applications.

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.
