The completely extracted DNA is retrieved from the membrane tube using an elution buffer. DNA is then ready for quality control checking and preparing for genotyping.

How does TE buffer protect DNA? | AnswersDrive

For binding, a buffer solution is then added to the sample along with ethanol or isopropanol. This forms the binding solution. The binding solution is transferred to a spin column and the column is put in a centrifuge. To elute, the wash buffer is removed and an elution buffer (or simply water) is added to the column.

Importance of Tris-EDTA (TE) Buffer in DNA Extraction

As we said earlier, the TE buffer has a significant role in eluting, washing and isolating DNA. It dissolves DNA or RNA and protects the nucleic acid from degradation. It is a major constituent of DNA extraction buffer which helps in the lysis of the cell wall and nuclear membrane.

However, read-to-use DNA kits, used commonly in recent times, don’t need a precipitation step. It directly dissolves DNA in the elution buffer. Traditional DNA extraction protocols rely on the precipitation step, it’s a kind of validation step, that indicates the presence of DNA. And that’s why scientists use this method so often.

How DNA Gel Extraction Works – Bitesize Bio

2. Dissolve the extracted DNA-containing gel in excess buffer. Using a specific buffer, which often contains a pH indicator, solubilize the gel-encased DNA. Usually the buffer and gel slice are heated until all of the gel is dissolved. The pH indicator is used to ensure that the buffer maintains the optimal pH for DNA binding.
