I found that I can regenerate the silica based spin columns as well, but they arent as robust to repeated uses. 2. For samples already purified that are not clean, try ethanol precipitation of the RNA to desalt. Le site web n’est pas disponible en franais dans son intgralit.
Denatured alcohol contains chemicals like isopropanol, methanol, and even benzene and these chemicals will not dry from the silica membrane and will carry into the DNA. I have tried each of the suggestions, but nothing seemed to make a big difference. I stuck it back in the vacuum centrifuge. close Follow Suzanne Kennedy Thank You! You've been added as a follower!

Problem: Inhibitors in the RNA The RNA has an abnormallylow 260/230 reading (below 1.0) or 260/280 reading or does not work in reverse transcription. When Gel Extraction Goes Wrong But even the simplest of procedures can go wrong. Solution: For low 260/230 readings, the best approach is to try more washes ofthe RNA sample. This can be caused by insufficient shearing of the genomic DNA during homogenization.
