Table 2. Photobleaching rates of TMR obtained from fits to fluorescent decay curves (estimates±95% confidence intervals).

Laser power(MW/cm2)	Delay (sec)	k (sec−1)
1.29	0	0.0079±0.000018
0.64	0	0.0020±0.0000014
1.29	0.2	0.0010±0.0000020

Unlike GFP, the single exponential model for simple photobleaching was sufficient to explain the TMR fluorescent decay.
