Pcr titer
SpletCPE observations were used as a positive indicator of the presence of virus. Viral concentrations, calculated by the method adapted from Spearman (1908) and Kärber (1931), were expressed as tissue culture infectious doses (TCID 50 )/midge. The assay could detect viral titres between 0.75 and 8.5 log 10 /TCID 50 /midge. SpletThis chapter provides step-by-step guidance for preparing viral DNA, conducting the real-time PCR assay, and using the resultant data to calculate a viral titer. 2 Materials 1. 10X DNase digestion buffer: 500 m M Tris-HCl, pH 7.6, 100 m M MgCl 2. 2.
