RedSafe Nucleic Acid Staining Solution

RedSafe Nucleic Acid Staining Solution (20,000x) is a new and safe nucleic acid staining solution. It is an alternative to the traditional ethidium bromide (EtBr) stain for detecting nucleic acid in agarose gels. It emits green fluorescence when bound to DNA or RNA. This new stain has two fluorescence excitation maxima when bound to nucleic acid, onecaentered at 309 nm and another at 419 nm., RedSafe Nucleic Acid Staining Solution.

Presentación: VIal 1ml / Conc 20.000X



RedSafe Nucleic Acid Staining Solution

In addition, it has one visible excitation at 514 nm. The fluorescence emission of Red Safe bound to DNA is centered at 537 nm. Red Safe Nucleic Acid Staining Solution (20,000x) is as sensitive as Ethidium Bromide (EtBr). The protocol is also similar  with a protocol of EtBr.  The Ames test proves lower mutation with RedSafe Nucleic Acid Staining solution compare with EtBr. In addition, RedSafe Nucleic Acid Staining Solution (20,000x) has a negative result in mouse marrow chromophilous erythrocyte micronucleus test and mouse spermaryspermatocyte chromosomal aberration test.

Therefore,  it is wise to choose Red Safe Nucleic acid Stainig Solution (20,000x) instead of EtBr for detecting nucleic acid in agarose gels.
