Tris-Glycine-SDS Rapid Electrophoresis Buffer (10×)

Description

Tris-Glycine-SDS Running Buffer (10X) is an optimized protein electrophoresis buffer designed for Tris-Glycine SDS-PAGE workflows. During routine protein gel electrophoresis, adjusting voltage conditions between stacking and resolving gels can increase operation time and reduce workflow efficiency. This rapid SDS-PAGE running buffer provides a simplified electrophoresis solution that enables constant voltage operation while maintaining reliable protein separation performance.

Compared with conventional Tris-Glycine SDS running buffer, this 10X electrophoresis buffer allows SDS-PAGE separation under a continuous 180–200 V constant voltage condition, reducing total electrophoresis time to approximately 30–35 minutes. The optimized formulation improves separation efficiency for low molecular weight proteins and enables clearer resolution of closely spaced protein bands, including improved visibility of 10 kDa and 15 kDa prestained protein marker bands when using polyacrylamide gels above 8% concentration.

Tris-Glycine-SDS Running Buffer (10X) is suitable for protein gel electrophoresis, Western blot sample preparation, protein molecular weight analysis, and routine SDS-PAGE applications. It provides a convenient alternative for laboratories requiring fast, reproducible, and efficient protein separation workflows.

Protocol Overview

Prepare the working electrophoresis buffer before SDS-PAGE experiments.

• Dilute Tris-Glycine-SDS Running Buffer (10X) with deionized water at a 1:10 ratio to prepare 1X working solution.
• Use the prepared 1X running buffer for standard Tris-Glycine SDS-PAGE electrophoresis systems.
• Perform electrophoresis under constant voltage conditions of 180–200 V.
• For optimized separation performance, select appropriate polyacrylamide gel concentration according to target protein molecular weight.

Prepared 1X working buffer is recommended to be used within two weeks. If precipitation occurs after low-temperature storage, gently warm the solution until completely dissolved and allow it to return to room temperature before use.
