Weighted mean univariate K-function curves of immunogold labeled GFP-HRASG12V under indicated conditions, n ≥ 15 for each condition. The gold point patterns were analyzed with univariate K-functions expressed as L(r)-r. The bar graph on the right shows the peak value Lmax of the L(r)-r curve, which represents the extent of GFP-HRASG12V nanoclustering. Values are normalized to DMSO average and represent mean±SEM (n ≥ 15 for each condition). Statistical significances of differences were evaluated in bootstrap tests.
