The Invitrogen Power Blotter Cassette XL is part of the Power Blotter System designed specifically for rapid semi-dry transfer of proteins from polyacrylamide gels to nitrocellulose or PVDF membranes in 5 to 12 minutes. The Power Blotter Cassette XL is the larger version of the standard-size Power Blotter Cassette, and can simultaneously transfer up to four mini-size or two midi-size gels. This item is made available as a replacement or additional cassette for the Power Blotter Station.

The Power Blotter Cassette XL can be used with Power Blotter Select Transfer Stacks for rapid transfers, the Power Blotter 1-Step Transfer Buffer for semi-dry transfers, or alternatively with traditional buffers for longer semi-dry transfers.
