Used in protein electrophoresis for separating proteins based on molecular weight. Ideal for running SDS-PAGE gels without the need for manual gel casting. Commonly used in western blotting workflows to analyze protein expression. The 8-20% gradient allows resolution of a wide range of protein sizes. 15-well format enables loading of multiple samples in a single run. 1.0mm thickness is compatible with standard electrophoresis chambers. Pre-cast design saves time and ensures consistent gel quality. Plastic backing provides durability and ease of handling during transfer steps.
