Hi,
I am using Ni affinity column to isolate my protein which came out
successfully with Imidazole. However, I found a lot (~100 mg) of protein
still sticking to the column and I eluted them out by stripping off the
Ni+2 from the column using EDTA. So, this solution now contains my protein
+ (may be some contaminant) + Ni and EDTA and is colored blue (as
expected). At this point I wonder if there is any way / standard practice
to separate the protein from Ni+2, so that I can re-utilize it.
Any help would be appreciated.
Regards,
Deb
