High quality chromatography, electrophoresis and blotting papers for use in gel transfer applications and chromatography techniques. These uniform, smooth, white sheets are the high purity, high quality, and high value standard. They are used in nucleic acid research such as Southern, Northern and Western blots, electroblotting and electrophoresis. Chromatography, electrophoresis and blotting papers are made from high purity and 100 percent compliant alpha cotton cellulose, using ultra-pure RO water and contain no additives that could cause increased backgrounds or other interference in detection systems. Controlled absorption, uniform absorption, consistency across the sheet, lot to lot consistency, high purity, no sizing or fillers, excellent wet-strength and handling, no hard spots or density variations, no airborne fibers, custom cut. This medium thick paper is recommended for general chromatography applications. Grade 238 is also ideal for use as wicks in protein or nucleic acid blotting to provide a uniform flow of buffer through the gel to the transfer membrane in a blotting sandwich. This is our most widely used blotting paper. Grade 238 is also suited for electrophoresis and the separation of inorganic compounds and for use in removing gels from glass supports.
