To determine the oligomerization state of your protein of choice you only need to:
​
Order your gene: Place the sequence of interest in the vector described in our publication.
​
Express your protein: In our study we could easily express the protein in a standard Escherichia coli expression strain under native conditions.
​
Purify the sample: Simply use a Ni affity chromatography to isolate your protein sample.
​
Determine the fluorescence anisotropy: Record the fluorescence polarization of your sample with a plate reader (Tekan, PolarStar) or a spectrophotometer (Cary).
​
Photobleach your sample: A simple setup to irradiate your sample is enough (laser diode pointing in a cuvette). The fluorescence intensity and anisotropy should be determined parallely.
