In article <01H9UED2XZKI009ZC9 at Post-Office.UH.EDU>, pedemonte at JETSON.UH.EDU (carlos h. pedemonte) says:

>l have tested out the SYBR Green I from Molecular probes. I have found that the dye can
be form 100 to 1000 times stronger (in a 254 nm transilluminator) than Ethidium Bromide on DNA probes or PCR products
from 40 to 200 basepairs. On larger DNA the SYBR Green I stain from 20 to 100 time stronger than
Ethidium Bromide. We have found that there is close to no background when using this dye. 
I have also more informasjon. My telephone is in Norway 47 22 93 41 94, Fax
