Protein ladders and standards for SDS-PAGE, western blots, and isoelectric focusing (IEF)
Choose from a variety of protein ladders (molecular weight markers) for protein electrophoresis and western blotting applications. Each protein standard or ladder is supplied in a ready-to-use format, eliminating the need to reduce, pre-mix, or add loading dyes. These protein 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 protein ladders are compatible for use in western blotting.

Western blot proteins ladders
Western Blot specific protein ladders are specifically designed for easy and convenient protein molecular weight estimation directly on western blots or indirectly by using various blotting detection systems (e.g. chemiluminescence, fluorescence, or chromogenic). The protein markers consists of recombinant proteins with an IgG binding site. The IgG binding site binds the primary or secondary antibody used for detection of the target protein, allowing visualization of the standard on the western blot. Direct visualization can be achieved through standard staining protocols (e.g. commassise stains), or indirect through chromogenic, chemiluminescent, or fluorescent detection systems.
