The iBlot® 2 Transfer Stacks are used to transfer proteins using the iBlot® 2 Gel Transfer Device. The iBlot® 2 Transfer Stacks are consumable stacks with integrated PVDF or nitrocellulose transfer membranes for dry blotting of proteins. Each iBlot® 2 Transfer Stack contains a copper coated electrode and appropriate cathode and anode buffers in the gel matrix to allow fast, reliable transfer of proteins.
