From: Analysis of the mechanical properties of wild type and hyperstable mutants of the HIV-1 capsid
Averaged measured point stiffness of recombinant CA assemblies (empty squares) and isolated HIV-1 cores (solid circles). Each value was calculated as the average of ~100 force–distance curves obtained from individual capsids. The average stiffness values derived from all of the measurements were plotted. Error bars represent the SE of the mean. The number adjacent to each data point indicates the number of capsid particles analyzed
