Optiblot gel electrophoresis and western blot reagents

SDS-PAGE gels for protein electrophoresis

Our Optiblot SDS-PAGE gels have improved performance over conventional gels and are easy to use. 

Gels are currently available in a 12 or 17 well format with 10 gels per pack. Cassette sizes are compatible with most common tank systems including XCell and Mini-PROTEAN gel tanks. Check for compatibility with your tank system.

​​Optiblot gels should be used with Optiblot buffers for optimal running conditions - buffer recipes are provided with gels or can be downloaded.
