ExcelGel™ precast gels for SDS-PAGE are available as homogeneous or gradient gels. The homogeneous gels have 25 preformed sample wells for sample volumes from 5-17 µl. The gradient gels use sample application strips (26 samples up to 40 µl, 52 samples up to 20 µl), paper pieces or sample droplets. All ExcelGel SDS Homogeneous and 8-18 gradient gels have a 33-mm stacking zone and a 77-mm separating zone.

ExcelGel gradient gels are recommended for use with Immobiline™ DryStrip gels,
