Precast mini and midi gels for fast and easy gel electrophoresis in laboratory and teaching applications. Q-PAGE™ Bis-Tris Precast Gels with optimized separation properties. Compatibility - Gel cassettes in Mini (10 × 8.3 cm) and Midi (10 × 10 cm) sizes, suitable for most mini gel tanks Easy Loading - numbered wells with separators Particularly Fast Separation - clear, sharp bands already after 30–40 minutes Gel cassettes with comb for well protection Clearer Separation of smaller proteins Especially Long Shelf Life – up to 12 months from manufacture when stored at 4 °C Wide Range of Applications – available as constant-concentration gels and gradient gels Easy Monitoring During Electrophoresis – transparent alignment lines on the gel cassette Sturdy Blister Packaging – for safe transport of the gels Bis-Tris precast gels are ready to use for SDS-PAGE in the MOPS (or MES) buffer system. The optimized gel formula provides improved resolution, more accurate results, and longer shelf life compared to conventional Laemmli Tris-HCl gels. Q-PAGE™ Bis-Tris Precast Gels are available as gradient gels (4–12%) and as gels with fixed polyacrylamide concentrations (8% and 12%) in 12- and 15-well formats. The cassettes come in two different sizes: Mini (W × L: 10 × 8.3 cm) and Midi (W × L: 10 × 10 cm). All Q-PAGE™ Bis-Tris Precast Gels contain stacking gels with 4% polyacrylamide. They are delivered sealed (preserved in Tris-Glycine buffer).
