Buffer solutions resist pH change because of a chemical equilibrium between the weak acid HA and its conjugate base A : When some strong acid is added to an equilibrium mixture of the weak acid and its conjugate base, hydrogen ions (H ) are added, and the equilibrium is shifted to the left, in accordance with Le Chatelier's principle. Because of this, the hyd… 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 double-stranded DNA …
