These are space-saving stock solution that is ideal for quickly preparing running buffer used for gel electrophoresis.

• Eliminates the possibility of powder remaining in a packet
• Eliminates time spent waiting for powder to dissolve
• Storage as concentrated stock minimises bench space needed for solutions

Tris-HEPES-SDS buffer - when diluted 20-fold in water, the solution yields 0,1 M Tris, 0,1 M HEPES, 3 mM SDS, pH 8
Tris-glycine-SDS buffer - when diluted 10-fold in water, the solution yields 0,025 M Tris, 0,192 M glycine, 0,1% SDS, pH 8,5
