TO-PRO 1 is a monomeric cyanine dye with a single cationic side chain and low base selectivity that is able to enter cells with damaged membranes and bind to nucleic acids, producing bright green fluorescence. In addition, TO-PRO 1 shows excellent staining results for diatoms that are challenging to stain. TO-PRO 1 is almost non-fluorescent when not bound to nucleic acids, but shows strong fluorescence when bound to nucleic acids, with a maximum excitation/emission light of 515/531 nm[1].
TO-PRO 1是一种具有单一阳离子侧链和低碱选择性的单体花菁染料,能够进入膜受损的细胞并与核酸结合,产生明亮的绿色荧光。此外,TO-PRO 1对染色具有挑战性的硅藻表现非常出色的染色效果。TO-PRO 1未结合核酸时几乎不发荧光,但当与核酸结合后表现出强烈荧光,最大激发/发射光为515/531 nm[1]。
