To extract gut microbial DNA, the following steps were taken: (1) A mixture of 1000 ul of CTAB lysate and 20 ul of lysozyme was prepared and the appropriate sample was added. The mixture was then incubated in a water bath at 65 °C for 2 h, followed by inversion and mixing to promo...
The mixture was then incubated in a water bath at 65 °C for 2 h, followed by inversion and mixing to promote lysis. (2) The resulting supernatant was cen- trifuged, and then an equal volume of phenol (pH 8.0): chloroform: isoamyl alcohol (25:24:1) was added. The mixture ...
PhenolpthaleinPhenolphthalein is the most widely used indicator in titration specifically acid-base titration that is usually carried out for the determination of the concentration of the sample. Some of the characteristics of phenolphthalein include its higher solubility in...
