Why take hours to elute individual gel slices when you can elute entire preparative gels in 20 minutes? Whether you're screening complex mixtures or purifying individual bands, the whole gel eluter can be your elution solution. Bio-Rad's Whole Gel and Mini Whole Gel Eluters are designed to elute and collect protein or nucleic acid fractions from preparative slab gels. The Model 422 electro-eluter elutes macromolecules from gel slices.

What is a Whole Gel Eluter?

The whole gel eluter and mini whole gel eluter are unique electroelution tools that simultaneously elute and collect multiple bands from whole polyacrylamide gels. These fast, efficient systems eliminate the tedious, time-consuming steps of slicing and eluting gel sections. They simply elute all biomolecules from the gel into liquid fractions.

Whole-Gel Eluter and Mini Whole Gel Eluter
The whole gel eluter and patented mini whole gel eluter are unique electroelution tools that simultaneously elute and collect multiple bands of biomolecules from whole preparative gels. These devices eliminate the tedious, time-consuming steps of slicing and eluting gel sections by simply eluting all biomolecules from the gel into liquid fractions. Applications include screening of crude mixtures of proteins to identify immunologically relevant antigens and purification of multiple bands of nucleic acids or proteins.

Benefits Include
• Rapid, reproducible elutions in 15–20 min
• Liquid fractions that allow immediate testing of eluate
• Elution of native, SDS, or IEF polyacrylamide gels
• Accommodation of gels up to 3.0 mm thick
• Recoveries averaging ≥70%
