Method |
Using fluorescence correlation spectroscopy (FCS), researchers measured in real-time the diffusion of 100
nM S1-Qdot conjugates upon binding to the immobilized
bacteria, which have been attached to a glass slide by
0.01% poly-L-lysine. |
Comments |
At the end of 1 h, the
addition of SDS lysed the bacteria, releasing the AMPQdot
into the supernatant (Figure 4A). These particles
have D = 7.29 µm^2/sec which is comparable to that of free Qdot diffusion in solution, and approximately 18 times
faster than that of bound particles (fig.4B) |
