We chewed pills with EtBr as kids in school to see if we brushed our teeth well

Wikipedia says it was used as a trypanosomacidal - It's being
discontinued not because
There exists a less toxic chemical than EtBr to stain DNA: SYBR safe
DNA stain (a fluorescence dye sold by a certain vendor). Another
benefit is to be able to use blue light, reducing UV/VIS light
exposure when handling gels.

SYBR Safe is about 10X less sensitive though.
I suspect that not many chemicals in the lab are less toxic/mutagenic than
EthBr. The classic Ames test shows that 5 ug

from our genetics department with regards to safety of that while

Sybr is just as toxic/poisonous/harmful as ethidium bromide, only
far more expensive. There have been very few tests concerning it's

Can you do the toothbrush test with SYBR Safe?
I wouldn't do that. As it is considerably more hydrophobic, I'd expect
If you can reproduce the crystals and have the material
1. Harvest several large crystals.
2. Make several transfers to fresh mother liquor to wash.
3. Dissolve in DNA loading dye without SDS
4. Run on a native gel (e.g. 6% polyacrylamide, 0.5XTBE, etc.).
5. Include positive control lanes for
Also this method might be useful if crystals tolerate the treatment.

If your DNA is small enough, you can run a control dsDNA lane on the gel. dsDNA
will show up on silver stain but the oligomer has to be small enough to enter
the gel.

Hi all,

recently,I got a crystal of protein-DNA crystal.i used silver stainto prove
that it is a protein crystal.Does anyone have method to detect if there is
DNA in the crystal.
any suggestion will be appreciated.
