Overview

Prestained Nautral Standards for SDS-PAGE and western blotting provide a quick and easy way to monitor protein separation during electrophoresis and to assess transfer efficiency on blots. Each lot of Kaleidoscope and SDS-PAGE prestained natural protein standards is individually calibrated for estimating the MW of sample proteins.

Kaleidoscope™ Natural Protein Standards

Kaleidoscope Prestained Natural Standards are broad range and have individually colored proteins to allow instant orientation on SDS-PAGE gels and western blots.
