This article discusses this effect in E. coli lysates. Please let us
know if you find something that works well with insect/mammalian
lysates or secreted proteins!

We tried that trick, which works amazingly well in insect cells, in
mammalian media, and it fails. It will depend on the exact media, obviously.

I had exactly the same problem. You should switch to Talon matrix
(Clontech). The cobalt ion is bound more tightly so stripping is
dramatically reduced. Furthermore, the Talon matrix is more specific
(then Ni Sepharose) for your His-tagged protein, so you have less
contaminants. I load two to

In case of cell lysates this may be a good idea since you can adjust the salt
concentration in your sample. In case of secreted proteins it is probably not
so good since the media contains ~150 mM NaCl. In my case this salt prevents
protein from bindinq to Q column.
Thank you anyway.
When mammalian cell culture is being loaded to GE HisTrap resin Ni ions
are being stripped off the resin, at least in my hands. Did any of you
have similar experience and if so what kind of work-around was found?
Volume is fairly large (3L) and concentration/dialysis have proven to

Hi,
I recently solved the structure of a mutant protein that contains a
single amino acid substitution.
Here are some data about the mutant:
resolution: 2.65 A
completeness: 99.9 % (100.0 %)
Rwork/free: 22.3/27.8 %
Rsym 15.6 (47.7) %
avg. mosaicity: 0.48°

The patent #7504486 you cited actually only covers 'A method of growing
a crystal of a 50S ribosomal subunit from Haloarcula marismortui', i.e.
the crystallisation method for the 50S subunit from this single organism

Hi Jan,
Always worth a try is to process the data in P1 then assigning the
symmetry in CORRECT - that way the cell constants can refine to what
they want to. It also means you can check that the symmetry actually
is cubic.
For the majority of data sets in my experience it makes little
difference
Dear Kumar,
This is perfectly normal. Long and flexible side chains e.g. lysines,
facing the solvent move around and have weak electron density. In fact,
I have not seen a structure where this is not the case. If you get
strong Fo-Fc density back, I would fit the side chains and not worry
about the
