A technique for identifying the presence of particular DNA sequences in a sample is manual Southern Blotting. In order to identify the target sequence, DNA must be transferred from an agarose gel to a nitrocellulose filter and then hybridised with a tagged probe. In order to confirm the existence of a single gene or a small group of genes, manual Southern blotting is typically utilised for low-throughput applications. Even though manual blotting requires more work than automated blotting, it is frequently more cost-effective when fewer samples need to be evaluated and there is a growing elderly population.
A molecular biology technique called automated Southern Blotting is used to find out whether a particular DNA sequence is present in a sample. Automation makes processes more accurate and efficient, resulting in quicker turnaround times, higher levels of reproducibility, and lower levels of result variance. Gene mapping and marker analysis are two common scientific uses for automated Southern blotting. Clinical uses for this kind of blotting include the identification of genetic disorders.
