CosmoPAGE Precast Gel
Cost-effective, Compatible with Bio-Rad Mini-PROTEAN
CosmoPAGE TG Precast Gels (Tris-Glycine) are ready-to-use acrylamide gels for SDS-PAGE running in Tris-Glycine buffer system. With unique formula, CosmoPAGE TG Precast Gels perform enhanced resolution, sharper bands, and longer shelf life as compared with conventional Laemmli Tris-HCl gels. The protein migration patterns in CosmoPAGE TG series, however, are similar with typical Laemmli Tris-HCl gels, and thus CosmoPAGE TG Precast Gels are compatible to traditional SDS-PAGE and subsequent analyses. CosmoPAGE TG Precast Gels are available in gradient (4 to 15%) and fixed (10%) concentrations of polyacrylamide in 15-well formats.
CosmoPAGE Bis-Tris Precast Gels are a high-performance and easy to use precast polyacrylamide gels for electrophoresis in Bis-Tris buffer system (MOPS or MES). The optimized gel formula allows CosmoPAGE Bis-Tris Precast Gel to show improved resolution, accurate results, and an extended shelf-life over conventional gels. CosmoPAGE Bis-Tris Precast Gels are available in gradient (4 to 12%) and fixed (12%) concentrations of polyacrylamide in 15-well formats.

Tips for using CosmoPAGE
Tips for using CosmoPAGE
 |
1. Before sample loading, rinse the wells to remove storage buffer. |
 |
2. Ensure tight-sealing of inner chamber when adaption (or fill outer chamber with buffer to the highest level.) |
 |
3. Under water flow, insertgel remover between gel and cassette from well site of gel. Slowly push gel remover to the bottom of gel until gel is detached from cassette. * Avoid diagonally peeling the gel from the corner or peeling from the bottm. |
Tips for Western transfer
 |
1. Assemble transfer sandwich by orientating cathode, sponge, 3 filter papers, gel, membrane, 3 filter papers, sponge, and anode. (The protein goes to the direction of cathode to anode.) |
 |
2. Remove air bubbles or excess buffer between gel and membrane by carefully moving roller over the membrane. |
 |
3. Maintain whole transfer process at low temperature. (Keep transfer tank in cold toom or on ice.) |
