NuPage Gels |
Mini-PROTEAN TGX/TGX Stain-Free Gels |
Side-by-side comparison of migration patterns of broad range unstained SDS-PAGE standards (1610317) run on NuPage ( ) and Mini-PROTEAN TGX and Mini-PROTEAN TGX Stain-Free gels ( ).
Criterion and Criterion Stain Free Precast Midi Gels
Precision Plus Protein Unstained Standards
Migration patterns (in kD) for protein standards on Criterion Tris-HCl and Criterion Stain Free Tris-HCl precast midi gels.
Criterion XT Bis-Tris Precast Midi Gels
Precision Plus Protein Unstained Standards
Migration patterns for protein standards on Criterion XT Bis-Tris precast midi gels. The banding patterns indicate the optimal separation ranges (in kD) for each acrylamide percentage in combination with the specified buffer system.
Tris-Tricine Midi and Mini Gels
Mini-PROTEAN |
Criterion |
Migration patterns (in kD) for protein standards on Mini-PROTEAN Tris-Tricine and Criterion Tris-Tricine Precast Gels.
Criterion XT Tris-Acetate Midi Gels
Precision Plus Protein Unstained Standards
Migration patterns (in kD) for protein standards on Criterion XT Tris-acetate precast midi gels with XT tricine running buffer.
Isoelectric Focusing (IEF) Gels
Migration patterns of proteins according to isoelectric point (pI) on Ready Gel IEF and Criterion IEF gels with Bio-Rad IEF anode and IEF cathode buffers.
Zymogram Gels
Zymogram
Migration patterns (in kD) for protein standards on Ready Gel zymogram and Criterion zymogram gels in Tris-glycine/SDS buffer. Migration patterns are based on the leading dye front being run to the bottom of the gel.
