PhastGel Homogeneous, Cytiva (formerly GE Healthcare Life Sciences)
PhastGel® Homogeneous are polyacrylamide gels with better protein separation for SDS PAGE.
- Select from homogeneous and gradient PhastGel® SDS PAGE gels
- Separate proteins and peptides on denaturing, native, and isoelectric focusing (IEF) gels
- Save time and improve reproducibility with precast gels, buffer strips, and staining kits
- Achieve detection sensitivity comparable to that of radioisotopes with ready-to-use silver staining kits
Homogeneous SDS PAGE gels offer better separation of proteins in a narrow molecular weight range. Unlike gradient gels, proteins separated in homogeneous gels do not reach a "pore limit" that would significantly slow (or almost stop) their migration. This can be exploited to optimise separation of proteins in a narrow molecular weight range from a complex sample.
PhastGel® Homogeneous media are available in three concentrations of polyacrylamide as indicated by their names: PhastGel® Homogeneous 7.5, 12.5, and 20 and PhastGel® High Density. The gels have a 13 mm stacking gel zone and a 32 mm separation gel zone.
