WebApr 1, 2024 · The quantitative parameters of bacteriophage-based qPCR detection were first tested by using serial 10-fold dilutions of purified DNA from brucellaphage S708. These experiments were done in three separate runs, each in duplicate, and yielded a log linear function between DNA concentrations and threshold cycle number (Ct), spanning a 9-log … WebThe effect is measured by a suitable test protocol. Serial dilutions of the patient serum are used and the highest dilution where the serum can still prevent complement activity in the indicator system is taken as the CFT titer of the sample. The tests are usually carried out on microtiter plates and the results are observed by eye.
