Mini gel welcome pack options

Four gel chemistries for tailored protein separations.

Bis-Tris and Tris-glycine are excellent for broad molecular weight range separation, and both feature a long shelf-life. The neutral pH of the Bis-Tris and the Bis-Tris Plus gel chemistries helps preserve protein integrity and offer fast run times.

The Invitrogen Novex Tris-Glycine Gels offer maximum protein separation and crisp, straight bands. NuPAGE Tris-Acetate Gels are recommended for the separation of high molecular weight proteins up to 500 kDa. Novex Tricine Gels are designed for the separation of low molecular weight proteins and peptides.
