Analysis of CacyBP/SIP dimer under in vitro conditions. A) SEC-MALS for CacyBP/SIP. LS5, light-scattering detector; UV, UV absorption detector; dRI, differential refractive index detector; QELS, quasielastic light-scattering detector. B) Analytical ultracentrifugation—sedimentation velocity analysis of CacyBP/SIP scanned at 280 nm. C) Analytical ultracentrifugation—sedimentation equilibrium data of CacyBP/SIP. The global fit to 6 data sets collected using protein at 3 different concentrations (3.2, 1.6, and 0.8 mg/ml). D) SEC-MALS for CacyBP/SIP dimerization domain.
