7.5 M stock solution (ammonium acetate, cat. no. 39750: 578.1 g/l) for precipitation of DNA. DNase/RNase not detected.Short oligonucleotides and free dNTPs do not coprecipitate with DNA when precipitated with NH4OAc. Two consecutive precipitation steps are enough to remove 99 % of free dNTPs. 7.5 M stock solution (ammonium acetate, cat. no. 39750: 578.1 g/l) for precipitation of DNA.

Product Detail
SERVA DNA Stain G is a safer alternative to traditional ethidium bromide stain for detecting nucleic acids in agarose gels. It is at least as sensitive as ethidium bromide and can be used in exactly the same way in agarose gel electrophoresis. SERVA DNA Stain G can be added to the gel solution, working dilution is 1:20,000 to 1:50,000.SERVA DNA Stain G emits green fluorescence when bound to DNA or RNA. It has one fluorescence excitation maximum at ca. 300 nm and another at ca. 450 nm when bound to nucleic acid.SERVA DNA Stain G is non-carcinogenic and according to the AMES test it causes significantly fewer mutations than ethidium bromide.

SERVA DNA Stain Clear G is a new, non-carcinogenic, much more sensitive and convenient version of our SERVA DNA Stain G. It can be used instead of highly carcinogenic ethidium bromide for detecting nucleic acids in agarose gels.SERVA DNA Stain Clear G emits green fluorescence when bound to DNA or RNA. It has two secondary fluorescence excitation peaks (ca. 270 nm and 295 nm) and one strong excitation peak centered around 490 nm. The fluorescence emission is similar to EtBr at ca. 530 nm when bound to nucleic acid.Pre-casting and post-staining protocols are applicable.1 ml of this stain is sufficient for 17 - 25 L of agarose gel.

Dithiothreitol, as well called DTT or Cleland's reagent, is a widely used reagent for maintaining thiol (SH) groups in reduced state. DTT quantitatively reduces disulfide groups (1) and is effective in sample buffers for reducing protein disulfide bonds prior to SDS gel electrophoresis (SDS-PAGE).It is not only less pungent and less toxic than 2-mercaptoethanol, but as well a seven fold lower concentration of DTT (100 mM) than of 2-mercaptoethanol (5 % v/v, 700 mM) is needed.DNase/RNase not detected. Oxidized DTT max. 0.5 %. Hygroscopic. Dithiothreitol, as well called DTT or Cleland's reagent, is a widely used reagent for maintaining thiol (SH) groups in reduced state.
