This video illustrates the setup and use of Bio-Rad's PROTEAN Plus multi-casting chamber to simplify the casting of acrylamide gels for protein electrophoresis.
You can use the PROTEAN Plus multi-casting chamber to cast up to 12 gels simultaneously, at 1.0, 1.5, or 2.0 mm thick. The chamber accommodates the PROTEAN Plus hinged spacer plates for both 20 and 25 cm wide gels. Acrylic blocks act as space fillers when fewer than 12 gels are cast, and a leveling bubble ensures level interfaces. Gradient gels can be cast through a bottom filling port using the Model 495 gradient former for reproducibility.
