WebAug 21, 2008 · MES is the buffer of choice for tissue culture media because it buffers in the appropriate range (pH 5.5–6.7) and supposedly has little or no effects unrelated to buffering (Banthorpe and Brown 1990; Good et al. 1966; Parfitt et al. 1988 ). In preliminary experiments, though, we observed an inhibitory effect of MES on rooting. 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. Good, Norman E. et al., Biochemistry, 5 ...
