Table 1.
Np | lp [μm] | ve,vr [μm/s] | τs[s] | A | fp [pN] | fth/fp |
---|---|---|---|---|---|---|
10 | 2.0 | 2.0 | 600 | 0.5 | 100 | 1.43 |
The number and mean length of pili are denoted by Np and lp, respectively. Their extension and retraction speed is ve and vr. The average time for which a pilus can withstand its load is τs. The probability to attach, the pulling force, and the ratio of the threshold force to the pulling force are denoted by A, fp, and fth/fp, respectively. For the BSA-coated surface, the value of A has to be set to 0.9.
