Problem:
Question 1: Virus particles are carefully isolated from an infected cell stock. You use this material to infect a culture of 10^6 cells with an MOI of 5 PFUs/cell. What is the maximum number of cells, which could be productively infected?
Question 2: Suppose you are asked to set up an infection in a virology lab. You are given a tube containing the virus stock in a freezer. You are asked to infect 99 % of cells with this virus stock. What MOI should you use?
I dont need long explanation. Just few sentences of expanation.
