Investigation of thermic transition and renaturation of high polymerized DNA extracted from thyroid nodule.
The study was carried out on 16 cases of mixed thyroid hypertrophy in which total or partial thyroidectomy was performed. Fragments collected intraoperatively from the thyroid nodule were used for extraction of high polymerized DNA. At the same time with quantitative evaluation of DNA, RNA and proteins were also assayed. The thermic transition mean temperature of the DNA extracted from the thyroid nodule is compared to other standards (DNA-HP-standard, calf thymus DNA, normal leukocytic DNA) and the thermic transition curves are presented. Hyperchromicity after thermic denaturation and renaturation is analysed and expressed in per cent values.
