DNA isolation / purification Cells - Primary cells Mouse embryonic fibroblast (MEF)

DNA isolation and purification is the first critical step in sample preparation that helps ensure optimal performance of downstream assays like PCR, microarrays, and sequencing. Failure in yielding high-quality DNA would be the major reason that DNA doesn't work for the downstream application. To circumvent this, one should follow the recommended storage conditions to minimize DNA degradation by nucleases and shouldn't overload the purification system.

DNA isolation column clogged

During centrifugation, the column got clogged and I was unable to continue with the protocol. How can I unclog it?

Upstream tips
DO NOT add bleach or acidic solutions directly to the sample-preparation
waste.
Downstream tips
- Include RNAse treatment for 15-20 min.
- Ensure EtOH is completely evaporated off of the column prior to elution. Adjust time from 1min to 5 min at 60`C
- Use prewarmed TE buffer to elute the DNA
