Another advantage of horizontal submarine gels is that multiple rows of wells can be formed, enabling the screening of large numbers of samples on a single gel. An agarose electrophoresis gel can be used to separate a much wider range of DNA and RNA sizes than a polyacrylamide gel. Horizontal submarine agarose gels are used for the majority of nucleic acid separations. Zymogram gels contain either casein or gelatin as substrates for proteases. For IEF using immobilized pH gradient (IPG) strips for the second dimension of 2-D electrophoresis, we offer precast gels that have combs that accommodate IPG strips. IEF gels are available with either a narrow pH range of 5–8 or a wider range of 3–10, with various numbers of wells and well volumes. Other types of precast electrophoresis gels that are available are gels for isoelectric focusing (IEF) for the first dimension of 2-D electrophoresis and zymogram gels for the detection of protease activity.
Immediately after electrophoresis, our stain-free gels can be viewed using a fluorescence imaging system without any staining blots can also be visualized immediately after transfer and again after development, allowing total protein normalization and quality-checking at every step of the western blotting workflow. Other buffer systems include Tris/tricine for separation of low molecular weight proteins, and Tris-HCl, Bis/Tris and Tris-acetate gels that can be used for separation of both native and denatured proteins.īio-Rad's stain-free electrophoresis gels are a recent innovation in protein electrophoresis. Unlike traditional Tris/glycine electrophoresis gels, TGX Gels can be run in very short times at high voltages with excellent results. Bio-Rad's TGX (Tris/Glycine eXtended) Electrophoresis Gels are a modification of standard Tris/glycine (Laemmli) chemistry with a longer shelf life and hence increased reproducibility over time. Precast electrophoresis gels are available in a wide range of acrylamide percentages (including gradient gels), well numbers, and buffer systems for both mini and midi electrophoresis gel formats. The ease, speed, large number of options - and importantly, the reproducibility of precast electrophoresis gels - make them an attractive alternative to hand casting. Precast electrophoresis gels are available for both vertical and horizontal systems. In addition to vertical PAGE systems, submarine horizontal electrophoresis gel systems are available in different widths and lengths. We also carry a wide variety of electrophoresis systems for nucleic acid separations. Configurable to accommodate 1–12 electrophoresis gels.A wide range of precast gels - for denatured protein and native protein separation or IEF.
