Chemotaxis migration coefficient

Based on the quantifled images, the chemotaxis partition coef-flcient (CPC) and the chemotaxis migration coefficient (CMC) can be calculated as described in (51). If a cell is detected on the high-concentration side (it migrates to the right), it is given a value of +1, whereas a cell detected on the low-concentration... 

Fig. 7. Quantification of co//RP437 chemotaxis in laFlow devices. Bacterial responses to gradients of 0-100 riM L-aspartate and 0-225 riM NiSO were quantified using image analysis. The data were used to calculate the chemotaxis partition coefficient (CPC) and chemotaxis migration coefficient (CMC). The CPC and CMC values shown correspond to the images shown in Fig. 4c and d.
