− | <p>To support our predictions for the chamber size, we made simple approximations for how the cells could bind to the membrane. The outcome of different membrane sizes, cell secretion rates and the needed size for specific proteins can then be evaluated. Previously experiments with the secretion of a SipA protein has been conducted. Here a secretion rate of 60 molecules per cell per second was found. The resulting production rate is then found. Here we assume a membrane size of 4 cm^2, a E. Coli attachment surface of 2 <span style="font-weight: 400;">μ</span> m^2 and we know the molecular weight of SipA is 74 kDa | + | <p>To support our predictions for the chamber size, we made simple approximations for how the cells could bind to the membrane.
