After cell lysis, the DNA needs to be selectively bound to a matrix, which can be a silica-based membrane, magnetic beads, or other suitable materials. The bound DNA is then washed with buffers to remove impurities and contaminants, such as proteins, polysaccharides, and other cellular debris.

8.5 Elution
The final step in the DNA isolation process is elution, where the purified DNA is released from the binding matrix using a suitable buffer. The elution buffer is typically a low ionic strength solution that allows for the DNA to be gently desorbed from the matrix without causing damage to the DNA strands.

8.6 Alternative Techniques
In addition to the above-mentioned techniques, there are alternative methods for DNA isolation, such as:
