For example, if 2x10 6 cells is infected by 50 m l of virus with a titer of 10 8 pfu/ml. The moi will be 0.05*10 8 /2*10 6 = 2.5. The fraction of cells that are not infected is P (0) = 1 - e -moi , i. e., 8% for moi = 2.5. projected price of lumber

In microbiology, the multiplicity of infection or MOI is the ratio of agents (e.g. phage or more generally virus, bacteria) to infection targets (e.g. cell). For example, when referring to a group of cells inoculated with virus particles, the MOI is the ratio of the number of virus particles to the number of … Vedeți mai multe The actual number of viruses or bacteria that will enter any given cell is a stochastic process: some cells may absorb more than one infectious agent, while others may not absorb any.
