Parameter values obtained upon fitting the insulin fluorescence emission kinetic traces recorded with emission fixed at 303 nm (exc. 276 nm) and 405 nm (exc. 276 or 320 nm).

Fitting parameter values and corresponding errors (standard errors), and root mean square errors were calculated after fitting the fluorescence emission kinetic traces recorded with emission fixed at 303 nm (exc. fixed at 276 nm, Figure 4B) and 405 nm (exc. fixed at 276 nm and 405 nm, Figures 4B and 5B) upon continuous 276 nm excitation to the equation F(t) = C1– C2.e−kt.

我们对在持续276 nm光激发下记录的两类荧光发射动力学轨迹进行拟合，拟合方程为F(t) = C1 – C2·e^(−kt)，并据此计算得到了拟合参数值及其对应误差（标准误，standard errors）与均方根误差（root mean square errors）。两类轨迹的具体记录条件如下：第一类的发射光固定于303 nm，激发光固定于276 nm（对应图4B）；第二类的发射光固定于405 nm，激发光固定于276 nm与405 nm（对应图4B和图5B）。
