Thermo Fisher Scientific high quality protein ladders and standards for protein electrophoresis

Protein standards and ladders for SDS-PAGE, western blots, and Isoelectric focusing (IEF)

Choose from a variety of protein standards and ladders (molecular weight markers) for protein electrophoresis applications. Each standard or ladder is supplied in a ready-to-use format, eliminating the need to reduce, pre-mix, or add loading dyes. These standards and ladders are consistent from lot to lot and are strictly quality controlled on appropriate gels to help ensure consistent band migration and intensity. All prestained ladders are compatible for use in western blotting.
