Semi-dry electrophoretic transfer cell. Blotting was first performed by Southern in 1975 with the transfer of DNA from agarose gels to nitrocellulose membranes. Since then, electrophoretic transfer has been used for DNA and RNA blotting. The Trans-Blot Semi-dry Transfer Cell incorporates the original concepts of semi-dry blotting with innovative features for rapid setup and ease of use. The pair of platinum-coated titanium and stainless steel electrodes ensures efficient, background-free blotting with trouble-free service.
