Rhinovirus and zinc part 4: cell toxicity
My experiments to understand how ZnCl2 inhibits rhinovirus replication have been thwarted by the finding that concentrations of the salt higher than 0.1 mM are toxic for cultured HeLa cells. The cells can tolerate 0.1 mM but not 0.2 mM ZnCl2. Last week I asked whether I could identify a concentration between 0.1 and 0.2 …
