![]() This system is best for transfer of large-format gels or multiple mini- or midi-format gels. The Trans-Blot cell accommodates three gel holder cassettes, each with a 16 x 20 cm blotting area. The Trans-Blot cell offers a choice of plate or wire electrodes and variable placement of the electrodes for either standard or high-intensity blotting options. Temperature regulation during transfer can be achieved through the use of a sealed ice-block or optimal cooling coil. The Criterion Blotter can transfer up to two Criterion gels (15 x 9.4 cm) or four mini gels simultaneously in 30–60 min. A self-contained Bio-Ice™ cooling unit absorbs the heat generated during transfer. The Mini Trans-Blot cell can transfer up to two mini gels (10 x 7.5 cm) in an hour and is available either as a complete apparatus or as a module that uses the buffer tank and lid of the Mini-PROTEAN ® Tetra cell for operation. ![]() The Mini Trans-Blot cell and the Criterion Blotter accommodate mini- and midi-format gels, respectively. Mini Trans-Blot ® Cell and Criterion™ Blotter These cooling systems prevent temperature fluctuations and overheating during high-intensity, extended, or native protein transfers Cooling mechanism - cooling systems consist of an ice block, a sealed ice unit, or a cooling coil that is coupled to an external cooling mechanism.Plate electrodes offer greater field strength than wire electrodes but wire electrodes may be more economical and generate less heat Electrodes - tank transfer systems use either plate or wire electrode cards.Cassettes are made of non-conductive material and designed to permit unimpeded flow of current and buffer through the gel and membrane sandwich Gel holder cassette - the gel and membrane sandwich is held together between two foam pad and filter paper sheets, and placed into the tank within a gel holder cassette. ![]() Ports on the lid allow connection points for the electrodes and are energized using an external power supply On the inside, the tank has slots for placement of the electrode cards, gel holder cassettes, and cooling element.
