WebJun 7, 2024 · Step 3: Alkaline Lysis. The lysis buffer (aka solution 2) contains sodium hydroxide (NaOH) and the detergent Sodium Dodecyl (lauryl) Sulfate (SDS). SDS solubilizes the cell membrane. NaOH helps to break down the cell wall, but more importantly, it disrupts the hydrogen bonding between the DNA bases, converting the … Webthese detergents with urea are the most effective for this purpose. During the ex-traction of proteins from bacterial cells under the conditions studied, the release of RNA into solution also occurs, while DNA mostly remains inside the cells. The proposed treatment does not break the bacterial cell walls; proteins probably are
WebThe anionic detergent, sodium lauryl sulphate (NaLS), seems to have a more specific inhibitory effect on growth of the Gram-positive Bacillus subtilis than on growth of the Gram-negative Escherichia coli. The specificity of anionic detergent towards B. subtilis has been traced to the difference in the nature of the cell wall.
