NuPAGE™ MOPS SDS Running Buffer (Powder)

Invitrogen NuPAGE MOPS SDS Running Buffer (Powder) is formulated for use with Bis-Tris gels to improve the resolution and band sharpness of medium- to large-sized proteins. Compared to MES-based buffers, the MOPS buffer system supports reduced protein migration rates for enhanced separation performance. 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:

• Improved resolution of medium- to large-sized proteins—slower protein migration with MOPS buffer enhances separation and band sharpness compared to faster MES-based buffers

• 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 laboratory workflows
• Room temperature storage and extended shelf life—powder format enables convenient storage with a two-year shelf life for inventory efficiency
• Reliable performance for routine SDS-PAGE—supports consistent and reproducible results across common protein electrophoresis applications when used under recommended conditions
