Guanosine as a UV Protectant - (Mar/10/2006 )

Hi everybody,

I read some threads in the forum about using Guanosine as a UV Protectant for DNA in Agarose Gels. I would like to do this, but what't the concentration you are using in your gels?
Thank you in advance four your answers

We use it at 0.28 g/L in 1x TAE. It is difficult to dissolve, so we stir it on a reasonably warm hot plate.
