4-20% Gradient Gels

4-20% gradient gels can be purchased from various suppliers for protein separation by electrophoresis. Precast gradient gels are solid, polymerized acrylamide slabs with a gradually increasing concentration. The pore size is large at the top (at 4%) and decreases near the bottom (at 20%), gradient gels can resolve the separation of a broader range of different molecular weights. Ready-made precast gels can help ensure efficiency and consistency across many experiments. Learn more details from the supplier page, including number of wells, compatible buffers, and more.
