A nucleic acid hybridization assay employing an immobilized or immobilizable polynucleotide probe selected to form DNA˙RNA or RNA˙RNA hybrids with the particular polynucleotide sequence to be determined. Resulting hybrids are detected by binding of an antibody reagent, preferably labeled with a detectable chemical group, selective for binding the hybrids in the presence of the single stranded sample and probe nucleic acids. No immobilization or labeling of sample nucleic acids is necessary and hybridization can be performed entirely in solution.
核酸杂交试验,采用固定或可固定的多核苷酸探针,与待测定的特定多核苷酸序列形成 DNA˙RNA 或 RNA˙RNA 杂交体。在单链样品和探针核酸存在的情况下,
抗体试剂(最好标记有可检测的
化学基团)可选择性地结合杂交体,从而检测所产生的杂交体。无需固定或标记样本核酸,杂交可完全在溶液中进行。
