After completing DNA extraction from whole blood using the QIAamp DNA Mini kit but obtaining no yield, I suspect the DNA might be retained in the column. How can I recover the DNA from the column.
For my DNA extraction, the last stage of elution is usually done with 70% ethanol, 80% ethanol (washing step), centrifugation, air drying the column and then eluting with hot water into another tube by centrifugation.
