| Method |
P.307 left column bottom paragraph: "[Investigators] used fluorescence photobleaching recovery (FPR) (refs 2, 7-9) to measure lateral transport. An intense laser light pulse irreversibly bleaches the fluorophore in a small region of the membrane. Transport
coefficients are calculated from rates of recovery of fluorescence in the bleached region due to entry of unbleached fluorophores from adjacent parts of the membrane. In principle, FPR can be used to distinguish among diffusion and mechanisms of systematic driven transport (ref 8)." |

P.308 middle column bottom paragraph: "(iii) Proteins on the plasma membrane labeled with FITC [fluorescein isothiocyanate] and TNBS [2,4,6-trinitrobenzene sulfonate] show similar rates, D~2×10^-10 cm^2/sec, and extents of fluorescence recovery." Gartner et al., 1975 PMID 1201086 p.972 2nd paragraph: "L6 is a permanent cell line derived from rat skeletal muscle (ref 1). L6 is particularly interesting because it differentiates in-vitro. Myoblasts proliferate and are the undifferentiated form of L6." |
