MDA stands for Multiple Displacement Amplification. It is a technique used to amplify DNA, particularly useful in scenarios where the starting material is limited, such as in single-cell genomics or when working with degraded samples.
Significance of MDA:
1. High Sensitivity:
MDA can amplify minute amounts of DNA, making it ideal for applications where only small quantities of DNA are available.
2. Uniform Amplification:
The method provides a more uniform amplification of the entire genome compared to other amplification methods, which can lead to better representation of the original DNA.
3. Application in Sequencing:
In the context of sequencing, MDA is used to generate sufficient quantities of DNA for sequencing libraries. After the initial sequencing read (Read1), MDA polymerase is employed to extend the DNA strands, allowing for further sequencing (Read2) and enhancing the overall signal during the sequencing process .
Overall, MDA is a crucial technique in genomic research, enabling the analysis of DNA from limited or challenging samples.
