Frequently Asked Questions

Frequently Asked Questions are available for this Product.


Optigels offer a range of large format pre-cast polyacrylamide gels ideal for use as the second dimension in 2D gel electrophoresis. Optigels are supplied using low fluorescing glass to allow compatibility with both traditional and fluorescent labeling systems, and are available prepared with bind silane if required. Optigels are compatible with several large format electrophoresis units including GE Healthcare′s Ettan DALTtwelve, Ettan DALTsix and BioRad Protean® Plus. All gels are cast with Laemmli (Tris-HCl) chemistry without SDS, providing flexibility of application. Developed for customers who require ultimate separation performance and reproducibility, our automated casting process provides ultimate gel-to-gel and batch-to-batch reproducibility for a broad range of homogeneous and gradient gels.
