National Diagnostics offers an improved method of nucleic acid visualization with the development of Nuclistain. Nuclistain is a positive stain concentrate for the rapid detection of double and single stranded DNA and RNA in agarose and polyacrylamide gels.

Nuclistain is intended as a replacement for the conventionally used ethidium bromide for the rapid detection of double and single stranded DNA and RNA in agarose and polyacrylamide gels. Its sensitivity is nearly comparable, with the capability of detecting as little as 10-50 ng of nucleic acid sample. The advantage of Nuclistain is that the results are visible under normal lighting conditions, eliminating the possibility of sample damage by UV radiation. Furthermore, Nuclistain visualization dramatically improves the yield of smaller and medium sized DNA (<500 bp) obtained by purification from agarose. Nuclistain binding is reversible and does not modify nucleic acids.

Nuclistain is extremely easy to use. One 25 ml bottle of Nuclistain will make 2.5 liters of stain solution. The separated DNA appears as dark blue bands on a light blue background.

Keep in a tightly closed container, stored in a cooled, dry, ventilated area. Avoid contact. Do not get in eyes, on skin, on clothing. Wash thoroughly after handling.

• UV free visualization of DNA and RNA
• Improves yield in PCR purification from agarose gels
• Easy and safe
