DNA Stain

There are several different stains that can be used to visualize and photograph DNA after separation by gel electrophoresis. Molecules of the dye adhere to DNA strands and fluoresce under UV light, showing where the bands are within the gel.

Hoechst stains are part of a family of blue fluorescent dyes used to stain DNA.There are three related Hoechst stains: Hoechst 33258, Hoechst 33342, and Hoechst 34580. The dyes Hoechst 33258 and Hoechst 33342 are the ones most commonly used and they have similar excitation/emission spectra.

    Netropsin dihydrochloride Modulator
    Netropsin (dihydrochloride) 是一种小分子(MGB) 小沟结合剂,抑制分离的拓扑异构酶的催化活性,并干扰拓扑异构酶 II 和 I 在细胞核中的可切割复合物的稳定性。Netropsin (dihydrochloride) 通过以非插入方式与 dsDNA 结合而具有潜在的抗生素和抗病毒特性,它通过干扰 HMGA1 DNA 与核心NOS2 启动子的结合来减弱 NOS2 的诱导作用,从而提高小鼠内毒素血症的存活率。DNA 溶液中 的 Netropsin (dihydrochloride) 由于其高结合亲和力和高结构稳定性而具有辐射诱导损伤的辐射保护能力,电离辐射产生的羟基自由基 (OH*) 不能对 netropsin-DNA 复合物进行放射性降解。
