iBlot 2 Transfer Stacks are used to transfer proteins using the iBlot 2 Gel Transfer Device. They are consumable stacks with an integrated nitrocellulose transfer membrane 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. This regular-size stack (13 cm x 8.3 cm) can be used with midi-size gels or two mini-size gels or E-PAGE 48 or 96 gels.

Nitrocellulose membrane
The nitrocellulose membrane (0.2-μm pore size) in this stack is composed of 99% pure nitrocellulose to provide high-quality transfer. The membrane is compatible with commonly used detection methods such as staining, immunodetection, fluorescence, and radiolabeling. The proteins bind to the membrane due to hydrophobic and electrostatic interactions. The protein-binding capacity is 209 μg/cm2.
