Whatman 3MM Chromatography Blotting Paper - 3030-861

Whatman produces its cotton-linter cellulose papers to consistent thickness, absorbency, and purity, with lot-level documentation analytical laboratories rely on. The 3MM Chromatography paper serves as both a separation support medium and a blot transfer wick. Consistent thickness and density give reproducible results lot after lot while carrying buffer steadily through the blot sandwich and stays in even contact with the gel surface. For clean Western and Southern results, additive-free 3MM Chromatography paper drives contamination-free electrophoretic transfer.

Key Characteristics

• Precut sheets drop straight into transfer stacks with no trimming
• Serves as a support medium for paper chromatography and electrophoresis
• Pure cotton-linter cellulose with no additives keeps transfers clean and reproducible
• Uniform capillary wicking carries buffer evenly through the transfer stack
• 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 from gel equilibration through the full transfer run. Send your transfer or chromatography setup to our technical service team and request a paper grade recommendation.

• Southern and Northern Blots - Carries buffer through capillary and electrophoretic transfer of DNA and RNA from gels to membranes.
• Capillary Transfer - Wicks transfer buffer upward through the gel and membrane to move proteins and nucleic acids by capillary flow.
• Blot Buffer Wicking - Carries transfer buffer evenly across the blot stack for complete, low-background Western and Southern blots.
• Gel Electrophoresis - Supports sequencing-gel lifting and electrophoretic work with a smooth, uniform cellulose surface.
• Paper Chromatography - Serves as a pure-cellulose support medium for separating sample components by capillary migration.
• Western Blot Transfer - Wicks transfer buffer evenly through the gel-to-membrane stack for complete, reproducible protein transfer.
