Description

This page describes the relationship between Arabinose concentration in the medium with light output. We used a [http://www.bmglabtech.com/products/microplate-reader/instruments.cfm?product_id=2 FLUOstar OPTIMA] microplate reader to quantify the light output. Protocol and plate reader settings used are given below.

Data

Figure 1 - Transfer function of BBa_K325219. The data points represent the mean of 11 values obtained for light output at 30 min interval from 450 min to 750 min after injection of D-Luciferin. These values are the mean of 3 readings as shown in Figure 3. The corresponding error bars represent an interval of twice the standard deviation across the 33 data points centred around the mean value.
Figure 2 - Maximum luminescence output of BBa_K325219 as a function of Arabinose concentration. These values are the mean of 3 readings as shown in Figure 3. The corresponding error bars represent an interval of twice the standard deviation across the 3 data points centred around the mean value.
Figure 3 - Evolution of luminescence with time at different Arabinose concentrations. The interval between measurements is 30 min. Mean values and error bars are based on 3 time repeats.
