Experimental Protocols

This mirrors files containing experimental protocols developed at the National Institutes of Health. 

The protocols contain detailed step-by-step information on how to plan, set-up and analyze experiments.

For more specific and up-to-date information please refer to the following books, which have specific information on SEDFIT and SEDPHAT functions as side-bars nested into the description of theory and experiment of analytical ultracentrifugation (AUC):




You can also consult the step-by-step protocol https://www.nature.com/articles/nprot.2017.064 (this is using fluorescence optical data, but the data analysis applies equally to other optical systems).
