DNA stains
Does anyone know what to stain DNA with and where to get it. After extraction, it would be great to look at it!
Re: DNA stains
We do not stain it . Students can see the strands in the t/tube or they can pull it out with tweezers.

Re: DNA stains
Any of the usual cell dyes will work. Toluidine Blue, Methylene Blue, or Aceto-Orcein will all stain the nucleus. Methylene Blue seems to work quite well, and is commonly suggested in text books.suea wrote:Does anyone know what to stain DNA with and where to get it.

If this is for the DNA extraction from dried peas, our biology teacher always recommends using bananna or kiwi fruit as substitutes for the peas to give better results.
