FIGURE 4.
Effect of indomethacin on nanocluster parameters of GFP-tH or GFP-tK. The immunogold point patterns analyzed in Fig. 3 were re-interrogated to provide an estimate of the number of gold particles per cluster and the total fraction of gold particles arrayed in clusters. Note that the number of gold particles can be converted to number of GFP molecules using the known capture ratio of this GFP antisera (≈0.45, Ref. 13).
