I have created GST-fusion proteins and purified them on glutathione
sepharose 4B columns, so the protein was eluted with 10mM glutathione in
50mM Tris-HCl pH7.5.
I want to use the fusion proteins to immunize some rabbits.
Do I need to get rid of the Tris to have the protein in water only (and if
so how do I do this)?
