Whatman 3MM Chromatography Blotting Paper - 3030-221

Whatman manufactures under Cytiva's quality infrastructure, drawing on a cellulose-paper heritage that spans chromatography, electrophoresis, and blotting. Smooth 3MM Chromatography cellulose holds spotted samples and wicks solvent across paper chromatography runs. Grade 3MM Chromatography paper supports separations, electrophoresis, and sequencing-gel lifting while keeping transfers clean through additive-free cellulose and draws buffer through the gel by uniform capillary action. Where capillary transfer carries the signal, the absorbent 3MM Chromatography wick moves buffer evenly through Western and Southern blots.

Key Characteristics

• Uniform capillary wicking carries buffer evenly through the transfer stack
• Precut sheets drop straight into transfer stacks with no trimming
• Pure cotton-linter cellulose with no additives keeps transfers clean and reproducible
• Serves as a support medium for paper chromatography and electrophoresis
• Supports Western, Southern, and Northern blot transfer as the wicking layer

Clean, additive-free paper keeps your blots free of the contamination that ruins detection. Uniform buffer wicking carries your transfer evenly to completion across semi-dry, tank, and capillary blotting setups.

• Sequencing Gel Lifting - Backs and lifts polyacrylamide sequencing gels on a smooth, additive-free cellulose surface for clean handling.
• Capillary Transfer - Wicks transfer buffer upward through the gel and membrane to move proteins and nucleic acids by capillary flow.
• Gel Drying - Backs polyacrylamide and agarose gels during drying for clean, even support and easy, reliable handling at the bench.
• Paper Chromatography - Serves as a pure-cellulose support medium for separating sample components by capillary migration.
• Blot Buffer Wicking - Carries transfer buffer evenly across the blot stack for complete, low-background Western and Southern blots.
• Western Blot Transfer - Wicks transfer buffer evenly through the gel-to-membrane stack for complete, reproducible protein transfer.
