从分子水平研究疾病,是当前世界上较为先进的技术。由于 DNA 重组技术的发展,使我们有可能较为方便地得到大量高纯度的特定 DNA 片段,经同位素标记制成探针后,可用分子杂交技术检测,鉴定特异的核酸序列。虽然分子杂交技术最初发展是用来筛选重组体的,但目前在医学生物学中得到了广泛应用,而在医学中应用最多的,要算是对病毒性肝炎的研究了,在短短的几年 Studying diseases at the molecular level is the most advanced technology in the world today. Due to the development of DNA recombination technology, it is possible to obtain a large number of high-purity specific DNA fragments conveniently. After the probes are made by isotope labeling, molecular hybridization can be used to detect and identify specific nucleic acid sequences. Although molecular hybridization was originally developed to screen for recombinants, it is now widely used in medical biology, and the most widely used in medical science is the study of viral hepatitis.
