WebBupH MES-Buffered Saline Packs are pouches of dry-blended powder that make optimized amine-free and carboxyl-free buffer. When dissolved in 500 mL of water, the buffer contains 0.1 M 2- (N-morpholino) ethanesulfonic acid (MES), 0.9% sodium chloride at pH 4.7 for carbodiimide (EDC) crosslinking and conjugation reactions. WebMES is used as a buffering agent in biology and biochemistry. It is utilized for resolving very small proteins on bis-tris gels. It is mainly used as a biological buffer in plant cell cultures. Buffer solutions are used as a means of keeping pH at a nearly constant value in a wide variety of chemical applications. Solubility. Miscible with water.
WebEDC crosslinking is most efficient in acidic (pH 4.5) conditions and must be performed in buffers devoid of extraneous carboxyls and amines. MES buffer (4-morpholinoethanesulfonic acid) is a suitable carbodiimide reaction buffer. WebIn brief, 1 m m OG488 NHS was dissolved in PBS buffer at a pH between 8.3 and 8.5. Kanamycin or Dextran was added to the solution with a molar ratio of amine groups to …

Webrecommended for any sulfonic acid buffer. If buffers must be nuclease-free, treat the water first, then add the buffer after autoclaving. When MES solutions are autoclaved, they turn yellow (although pH does not change measurably). The identity of the yellow breakdown product is unknown.4 References 1.
