Aggregation Prevention Assay for Chaperone Activity of Proteins Using Spectroflurometry
[Abstract] The ability to stabilize other proteins against thermal aggregation is one of the major characteristics of chaperone proteins. Molecular chaperones bind to nonnative conformations of proteins. Folding of the substrate is triggered by a dynamic association and dissociation cycles which keep the substrate protein on track of the folding pathway ...

[Abstract] Zonal sedimentation analysis on sucrose gradients allows estimation of the molecular size of an individual protein or a protein complex by centrifugation at a constant speed under nondenaturing conditions. This method is particularly suitable for globular proteins like the influenza A virus (IAV) protein hemagglutinin (HA). Here, I describe step ...
