Fig 3. Temporal evolution of radial concentration profiles in a sedimentation velocity experiment with bovine serum albumin in a “prime gray” photopolymer centerpiece.

Panel A: Absorbance data acquired at a rotor speeds of 50,000 rpm at a series of time points (symbols, only every 3^rd data point of every 2^nd scan shown, with color temperature indicating progress of time). The c(s) fit (lines) results in an rmsd of 0.0065 OD₂₈₀, with the residuals shown in the small plots as residuals bitmap and superposition. Panel B: The corresponding c(s) distribution (magenta), and for comparison the c(s) distribution from a control in the same run using a standard Epon centerpiece (black); microgreen (green); Xtreme white (blue dashed); in-house clear (cyan dotted).
