. Web To determine the concentration in PFUmL of the original sample multiply by an additional dilution factor of 10 since only 100 μL of sample was plated. An average of. 14 293 cells seem to have a lag.

Web Based on the extinction coefficient of wild-type Ad as determined by Maizel et al89 the concentration of viral particles is calculated as follows. Multiply that number by the reciprocal of the dilution used to make that plate and convert. Ie Calculate the mean.

For example if 2x10 6 cells is infected by 50 m l of virus with a titer of 10 8. O 175 x 107 PFUmL O 175 x 106 PFUmL O 175 x 109 PFUmL O 175 x 10-8 PFUmL. Web CFUml No.

Total PFU needed PFUml. You have a virus with a titer of 13x1011 PFUml and a well that contains 18x106 cells. Plaque forming units pfu is a measure of number of infectious virus particles.

You have a virus with a titer. Web If you overlay 100μL which is equivalent to 01 mL this solution onto agar plate and got 36 colonies the number of colony forming unit per mL is calculated as. Ask Question Asked 4 years 3 months ago.

Web The basis of the plaque assay is to measure the ability of a single infectious viral particle to form a plaque on a confluent lawn of susceptible cells. 1 X 1076 PFUml 4 x 107 PFUml use the 10X key on calculator to convert Between duplicates the difference in titers should be. Web How is PFU calculated.
