A method for optical measurement of a multi-stranded nucleic acid which comprises the step of bringing a compound into contact with a multi-stranded nucleic acid wherein said compound is capable of interacting with the multi-stranded nucleic acid, wherein the compound has the following properties:
(a) the compound can exist in a substantially colorless and non-fluorescent state under at least one condition in an aqueous solution in the absence of the multi-stranded nucleic acid, and
(b) when the multi-stranded nucleic acid is allowed to exist in the condition defined in the above (a), the compound changes to a substantially colored state based on an interaction with the multi-stranded nucleic acid and substantially expresses fluorescent property based on said interaction.
一种用于光学测量多股核酸的方法,包括以下步骤:将一种化合物与多股核酸接触,其中该化合物能够与多股核酸相互作用,该化合物具有以下特性:(a)在无多股核酸存在的情况下,在水溶液中至少有一个条件下,该化合物可以存在于基本无色且不发荧光的状态;(b)当多股核酸被允许在上述(a)所定义的条件下存在时,该化合物会因与多股核酸的相互作用而转变为基本上带色的状态,并基于该相互作用表现出基本上发荧光的特性。
