NuPAGE™ MES SDS Running Buffer (Powder)

Invitrogen NuPAGE MES SDS Running Buffer (Powder) is formulated for use with Bis-Tris gels to enable enfast, high-resolution SDS-PAGE protein separations. The MES buffer system supports rapid protein migration and is recommended for resolving small- to medium-sized proteins. Supplied as a dry powder, this running buffer enables flexible preparation, room temperature storage, a two-year shelf life, and is designed to be a convenient and reliable choice for routine electrophoresis workflows.

Features and benefits include:

• Fast separations for small- to medium-sized proteins—MES supports faster protein migration than MOPS-based buffers, helping reduce run times while maintaining resolution
• Optimized for Bis-Tris gel workflows—designed for use with Bis-Tris gels including both NuPAGE Bis-Tris and Bolt Bis-Tris Plus gels
• Powder format for flexible preparation—prepare fresh running buffer as needed to support consistent electrophoresis performance and simplify storage
• Room temperature storage and extended shelf life—powder format supports convenient storage with a two-year shelf life for inventory efficiency
• Reliable performance for routine SDS-PAGE—supports consistent results across common protein electrophoresis workflows when used under recommended conditions
