Whatman 3MM Chromatography Blotting Paper - 3030-335

Whatman's brand recognition and documented performance history support specification of its papers in standardized blotting and chromatography protocols. Medium-weight 3MM Chromatography paper draws transfer buffer through the blot stack by uniform capillary action. High-purity cotton-linter cellulose protects sensitive transfer and detection steps and supports paper chromatography and electrophoretic separations. For clean Western and Southern results, additive-free 3MM Chromatography paper drives contamination-free electrophoretic transfer.

Key Characteristics

• Uniform capillary wicking carries buffer evenly through the transfer stack
• Pure cotton-linter cellulose with no additives keeps transfers clean and reproducible
• Supports Western, Southern, and Northern blot transfer as the wicking layer
• Smooth surface stays in even contact with the gel for consistent results
• Medium 0.34 mm thickness holds ample buffer for even, complete transfer

Steady buffer wicking and even gel contact keep every band transferring cleanly across the membrane. Pure cotton-linter cellulose keeps your transfers clean and reproducible with no additives to contaminate sensitive detection.

3030-335

• Paper Chromatography - Serves as a pure-cellulose support medium for separating sample components by capillary migration.
• Gel Drying - Backs polyacrylamide and agarose gels during drying for clean, even support and easy, reliable handling at the bench.
• Sequencing Gel Lifting - Backs and lifts polyacrylamide sequencing gels on a smooth, additive-free cellulose surface for clean handling.
• Gel Electrophoresis - Supports sequencing-gel lifting and electrophoretic work with a smooth, uniform cellulose surface.
• Western Blot Transfer - Wicks transfer buffer evenly through the gel-to-membrane stack for complete, reproducible protein transfer.
• Southern and Northern Blots - Carries buffer through capillary and electrophoretic transfer of DNA and RNA from gels to membranes.
