Comment:
Sodium cacodylate is a widely used buffer for different assays\: (I) enzyme reaction buffer (e. g. ref. 1, 4)\: labeling of DNA at the 3' end with [α-32P]ddATP in 140 mM sodium cacodylate buffer (pH 7.2, ref. 4; pH 6.8 ref. 1) and terminal transferase; (II) reaction buffer for the chemical modification / cleavage, e. g. for the sequencing of DNA (50 mM, pH 8.0, ref. 5); (III) fixation of tissue, membranes and cells with glutaraldehyde or formaldehyde, respectively, in fixation buffer (e. g. ref. 2, 3). The working concentration ranges from 10 - 50 mM and a pH value of 7.2. Please note, that cacodylate inhibits the alkaline phosphatase in a concentration dependent manner in the cytochemical assay for this enzyme. As an alternative, the authors recommend the use of a NaOH-Pipes buffer (2)
