Ba, Desulfobacteraceae subgroup Seep-SRB1a. Therefore, with 70% formamide, the annealing of DNA strands is completely inhibited at 41–50°C, whereas RNA-DNA hybridization proceeds to its full extent (37, 38). But we also know there is a double bond and this acts like a single bond (from the principles of hybridization). Importance of formalin fixing conditions for HER2 testing in gastric cancer: immunohistochemical staining and fluorescence in situ hybridization.
