I have a small well 384 plate from IDT with around ~10ul per well. The wells seem to evaporate? at the edges or certainly disappear over time?

Hi This is very odd. Whenever I come back to the plate and defrost it (At room temp for a couple of hours) wells that I know had previously been filled have become void. Some of them I have now...

Mangal Singh

Yes you can, anything unbound to DNA will be removed in the wash step. See the nucleotide length that can efficiently bind to the column.

Steve Hawkins

I agree with the previous answer, TCEP is commonly used in the disruption process during column based RNA extraction and is removed during column washing, this will be the same with your PCR product.

Simon Butler

Thank you Mangal Singh and Steve Hawkins. Succinct and helpful.
