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. WebMost of the experiments were conducted in a near-neutral pH by using a 0.60 mM 2-(N-morpholino)ethanesulfonic acid (MES) buffer solution, a non-coordinating tertiary-amine buffer with a pK a of 6.06. The pH was adjusted to 7.40 ± 0.05 using NaOH. The pH measurements were made using a Schott Instrument Lab 850 pH meter. The kinetic …
