General description

MOPS – EDTA – Sodium Acetate (MESA) is the most commonly used running buffer for RNA electrophoresis prior to Northern blotting procedures. Applied voltage of 5 V/cm is recommended for maximum resolution.

Application

Suitable for use when making formaldehyde-agarose gels and associated running buffer for RNA electrophoresis.

Preparation Note

1x MESA buffer contains:

40 mM MOPS
10 mM sodium acetate
1 mM EDTA (pH 8.3)

Dissolve entire contents of bottle in a final volume of 1L molecular biology grade water. This produces a 10x MESA stock solution that can be further diluted as needed.

Journal of bacteriology, 184(9), 2491-2499 (2002-04-12)

Two operons have been cloned from Anabaena sp. strain PCC 7120 DNA, each of which encodes the three core subunits of distinct mitochondrial-type cytochrome c oxidases. The two operons are only 72 to 85% similar to one another at the
