Fluorescence Methods for Ca 2+ Exchange 93 1. Before determining the Ca off-rate of a fluorescent Ca 2+ -binding protein it is important to run fluorescent spectra of the protein in the Ca 2+ free and Ca 2+ bound state (as in Fig. 1). This spectra shows that F19W undergoes a large increase in TRP fluorescence with Ca 2+ -binding. When a Ca 2+ -F19W solution is rapidly mixed with EGTA, its fluorescence should decrease as Ca 2+ dissociates. Having the fluorescence spectra allows one to choose the correct wavelengths or filter system with which to monitor this fluorescence decrease. For monitoring F19W TRP fluorescence, we use a filter (UG1) that transmits light from 320 to 380 nm. Excitation was at 285 nm as in Fig. 1. 2. For measuring Ca 2+ off-rates using TRP fluorescence: Fill drive-syringe A with 2 mL of 4 µM F19W + 200 µM CaCl 2 in a 10 mM MOPS, 90 mM KCl, pH 7.0 buffer, and the other drive-syringe B with 2 mL of the same buffer + 5 mM EGTA. Make sure the temperature in the drive syringes has equilibrated to the desired temperature, in this case 10°C. With our Applied Photophysics stopped-flow, each time the pneumatic drive is activated to initiate a shot, it drives 100 µL of syringe A and 100 µL of syringe B into the mixing chamber and mixing is complete in 1.6 ms. We make three shots to flush the mixing chamber of wash solution (nanopure water) and then begin to collect data. Typically 5–10 shots are collected, averaged, and fit with an exponential equation. Figure 2 shows the time dependence of the EGTA-induced decrease in F19Ws fluorescence when six shots are averaged. For data analysis, we fit the data after mixing is complete (1.6 ms) with a single- or double-exponential equation using the nonlinear Levenberg- Marquardt algorithm. As shown in Fig. 2, F19Ws TRP fluorescence decreases upon Ca 2+ dissociation as a single exponential (based on χ-squared values and distribution of residuals) at a rate of 310/s. 3. After each series of shots, both syringes and the mixing chamber are flushed with 3–5 mL of nanopure water to remove protein and CaCl 2. 4. For the control shots, syringe A has the same F19W + 200 µM CaCl 2 solution as aforementioned and syringe B is replaced with a solution of the same buffer and 200 µM CaCl 2. 5–10 shots are averaged and this data is overlaid with the EGTA shots above. The control shots give the fluorescence intensity of the Ca 2+ saturated state and reveal any photobleaching that might be occurring. In our experiments, these control traces were flat lines starting at 4.6 V fluorescence. This showed that no bleaching was occurring over the time range of data acquisition and no correction for bleaching was required. If the control shots exhibit a linear decrease in intensity with time, then photobleaching is occurring and the control shots should be subtracted from the data before fitting. The fact that the control trace starts at 4.6 V also indicates that some of the decreases in fluorescence was lost in the mixing time of the instrument (see Note 5). 3.3. Measurement of Ca2+ Dissociation from <strong>Protein</strong>s Using Quin-2 Fluorescence The fact that EGTA induces a decreases in F19W fluorescence at 310/s does not prove that this is the rate at which Ca2+ is dissociating from this protein. It
