highly significantp < 10 −4
Our model selection again identified three kinetically distinct populations of σ2-containing CCPs ( Figure 2 C and 2 D, Tables S1 and S2 ); the preference for three versus two subpopulations was weaker but still highly significant ( p < 10 −4 as compared to p < 10 −10 in LCa-EGFP–expressing cells).
