Oligonucleotide building processes are monitored by means of an oligonucleotide probe which in one embodiment is labelled at one end with a chemiluminescent label and at the other end with a quencher molecule. The conformation of the oligonucleotide probe changes according to whether the probe hybridises with a substantially complementary nucleic acid sequence. In the non-hybridised state the chemiluminescent label is sufficiently close proximity to the quencher that the chemiluminescent emission is substantially attenuated, but in the hybridised state the separation is such that there is little or no attenuation. Particular probes and emitter/quencher pairs are disclosed.
寡核苷酸构建过程通过一种寡核苷酸探针进行监测,其中在一种实施例中,该探针的一端标记有
化学发光标记,另一端标记有猝灭剂分子。寡核苷酸探针的构象会根据探针与基本互补的核酸序列杂交与否而改变。在非杂交状态下,
化学发光标记与猝灭剂足够接近,导致
化学发光发射被大幅衰减,但在杂交状态下,它们之间的距离足够远,几乎没有衰减。具体的探针和发射器/猝灭器配对被披露。
