Biotium Ember500 RNA Prestain Loading Dye
Biotium has released the Ember500 RNA Prestain Loading Dye, which is more sensitive than conventional prestaining with ethidium bromide (EtBr) and is compatible with blue LED gel imagers, unlike EtBr. The prestain also includes formamide as well as electrophoresis tracking dyes, allowing sample denaturing, loading, tracking, and staining in a single step. In addition, Ember500 stains both RNA and DNA, allowing the detection of contaminating genomic DNA in purified RNA samples, Biotium said. The prestain will be supplied at a 2X concentration and will be available in 4 x 1 mL and 1 x 250 uL sizes priced at $350 and $60, respectively. Free samples will be available for a limited time, the company added.
