I have one 100bp and 1kb dna markers in the lab nearly and their expiry was in 2015, stored in -20 since then, will they still work well?
If they have been stored frozen then I expect them both to work well. DNA is very stable
Yes, if it was stored at -20 ℃, it should not be a problem. But, you can always check it on gel. It is an easy thing to do.
I agree with Paul Rutland
It will work...
I will work if stored at -20
yed, if it stored in at -20
