– 1) Non-toxicity: The unique oiliness and high molecular weight characteristics of CelRed prevent it from penetrating cell membranes into cells. Ames test results also show that the mutagenicity of CelRed dye is much less than that of EB. 2) High sensitivity: suitable for electrophoretic staining of various fragments of different sizes, with less influence on nucleic acid migration than SYBR Green I. 3) High stability: suitable for preparation of agarose gel by microwave or other heating methods;Extremely in an acid or base buffer at room temperature
