WebJun 7, 2024 · 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 (dsDNA) in the cell, … WebApr 3, 2024 · Modified PEG-NaOH gDNA extraction. Extraction was performed in a 1.5-mL tube containing 100 µL of bacteria in a broth culture or from a colony suspended in saline. It was centrifuged at 6082 × g for 4 min. Ninety microliters of the supernatant were withdrawn, and the bacteria were suspended in the remaining 10 µL.
