Hello Amala, Usually Ni-NTA won't have this kind of problem of binding. Probably your protein is have interaction with hexagon his tag which is affecting its affinity towards beads. You can try putting tag in C- terminal end of the protein. On Mon, 13 Aug 2018, 8:02 pm Artem Evdokimov, wrote:

Hi all, I am purifying a basic protein with pI 7.8. I used 50mM tris 8.8, 300 mm NaCl, 5% glycerol, 0.1mM PMSFand 5mM beta ME in the buffer and performed affinity purification. Eluted with 200mM imidazole. While elution I could see slight turbid in eluted protein (I get pure protein, single ban

Hi, I have used tev protease for tag cleavage during dialysis. In my case always tev got precipitated not my protein. And cleavage was always complete. I havE checked on the sds - page as wel. On 2 May 2015 23:27, "Giulliana Rangel" wrote: > Dear all, > > I'd like some help about my protein cause

Hi, One more suggestion would be autoinduction. This may not help in all the conditions but still can be checked. Instead of IPTG use 0.2% lactose in media and check for expression at different temperature. Hope it helps. All the best. On 17 Oct 2014 21:55, "Roger Rowlett" wrote: > You've trie

[ccp4bb] How to separate BSA present in Thrombin

2014-10-08 Thread Manjula Ramu
Hi all, My protein size is nearly the same size of BSA and it has His tag. If I have to cleave the tag I have to use Thrombin which is having huge amount of BSA in it. Now how will I separate this BSA from my protein. Thanks and Regards, Manjula R Research Scholar Department of Biophysics Nationa
