Why does GFP dimerises at higher concentrations (5mg/ml) ? What is the nature of the interaction which causes this dimerization ?

02 February 2019 0 5K Report

I have purified EGFP-His tagged protein. The protein is purified in a dimer form. The concentration of the purified fractions are high (5mg/ml). I want to know what causes the dimerization and what forces are involved in it?
