HiMedia's Filter Paper for Blotting are pre-cut cotton sheets with a dimension of 7.5 cm x 10 cm and ≈0.80 mm thick, suitable for wet, semi-dry and electrophoretic transfer of proteins or nucleic acid from polyacrylamide gels or agarose gels to nitrocellulose, PVDF, or other membranes. They are suitable for use with alcohol or other organic solvents commonly used in protein and nucleic acid blotting applications. The 7.5 cm x 10 cm size is compatible with almost all mini-size hand-cast or pre-cast gels.
