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.

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.
