Safety Data Sheet

Safety Data Sheet



Choose midi Criterion XT Bis-Tris Protein Gels for versatile SDS PAGE.  This gel can be run with two different denaturing running buffers, XT MES and XT MOPS, providing different separation profiles.

  • Use of different running buffers to expand the utility of this gel
  • Neutral pH (pH 6.4) delays acrylamide hydrolysis as compared to traditional Laemmli systems
  • 12-month shelf life
  • Run 2-D electrophoresis in less than a day
  • One well for markers or other reference

The two running buffers and three different percentage XT Bis-Tris gels combine to provide six different migration patterns.
