Viridi DNA Stains

Viridi Easy DNA Stain is the 6x gel loading buffer formulation of Viridi that is added directly to the DNA sample just before loading onto the gel. It’s very quick and easy!

This formulation is ultra-convenient to use, with no need to dilute from stock: simply add to your DNA sample and load on the gel.

After electrophoresis, the gel can be viewed immediately without any need to incubate in stain. The sensitivity of Viridi Easy is approx. 1 ng DNA / band.

Adding to the convenience, the minimal amount of stain involved makes for a much easier clean-up than after conventional staining in a bath.

Viridi Vivid DNA Stain is the ultra-sensitive formulation of the Viridi DNA Stain capable of detecting 100pg of DNA. It can be used in 2 ways:

1. Used in-agarose
Viridi Vivid is added to the molten agarose before pouring the gel. After electrophoresis, the gel can be viewed immediately without any need to incubate in stain. The sensitivity is about 0.25 ng DNA / band and the effects on migration rates are minimal, even at higher DNA loads.

2. Classic post-staining
The DNA samples are first run out on an agarose gel. This approach avoids the possibility of any DNA-stain interactions on migration rates and is recommended for the most accurate estimation of DNA band size.

Subsequent to electrophoresis, the gel is incubated for 30 minutes in a bath of Viridi Vivid. The post-staining method offers the most sensitive detection – less than 0.1 ng DNA / band.
