The optimal values of parameters and the R2 of fitted Eqs 1 and 2.

A–The growth medium, B–the low-conductivity buffer, C–the hyperosmotic buffer, D–the high-conductivity buffer, E–the buffer with calcium. Values in bold and the symbol next to them emphasize if the cells were desensitized (S2/average(S1)↓), sensitized (S2/average(S1)>1, symbol ↑) or if the trains were equally effective (S2/average(S1)≈1, symbol ≈). The numbers after ± sign define 95% confidence interval. The graphical representation of S2/average(S1) and τ2/average(τ1), based on experimental uptake results in Fig 4, is in Fig 5.
