Protein Gels
Featured protein gel categories
Bolt Bis-Tris Plus Gels
Broad molecular weight protein separation with high sample resolution, better sample integrity for high sensitivity applications. Unique wedge well provides easier-to-load, larger capacity wells.
NuPAGE Bis-Tris Gels
Broad molecular weight protein separation with high resolution and sample integrity that are ideal for applications where protein integrity is crucial.
Novex Tris-Glycine Gels
Robust gel for a wide range of sample types and molecular weights, providing sharp, straight bands and easier-to-load, larger capacity wells.
NuPAGE Tris-Acetate Gels
High performance gels optimized for separation of high molecular weight proteins.
Specialized Gels
Tricine gels for low molecular weight proteins, Invitrogen NativePAGE gels for superior optimum resolution of native proteins, IEF gels for isoelectric focusing, and systems for high-throughput, 2D electrophoresis and protease separation.
SureCast Gel Handcast System
Pour your own gels with this system that includes a mini gel casting station, glass plates, spacers, combs, and optimized reagents.
