Hi Monica=2C

If your protein is in the pellets I hope you are using denaturing condition=
s to solubilize it before purification over Ni-NTA.

solubilize the protein in urea or guanidine for one hour and spin down to g=
et a clear lysis solution before you proceed to further purification steps =
Ni-NTa or gel.
