Fatty acids are very soluble in glycerol or the PEGs.
Most proteins tolerate high concentrations (30-50%) glycerol and PEGs.�
So, it is quite possible to make a solution that will allow the protein
crsytal and the ligand to both be in the same solution.
One of my former colleagues was in ch
Hi Frank,
heme becomes near completely insoluble when it dimerizes. Fatty acids
are also very insoluble. It is quite hard to get them into HSA, as far
as I remember.
Cheers,
Tim

And then of course, you need to decide whether you at all care to know
anything about a compound that is so insoluble that it needs that kind
of treatment :)

Hi
As total insolubility does not exist, I regularly use another method,
which is to deposit a grain of the ligand directly into the drop.
In this case, we no longer control the concentration. The goal is to
regularly freeze crystals (1 hour, 2 days, 1 week ..). Depending on the
results, it

Dear Gourab,
You might just want to add the ligand in pure, solid form to the edge of the
crystallization drop. This worked in our case beautifully (see Angew. Chem.
Int. Ed. 2012, 51, 3354). We had to soak it for 4 weeks.
Good luck!
Best regards

Hello everyone,
I am finding it difficult for getting a ligand density inside the protein
as the ligand is very much insoluble. It's only soluble in 100% DMSO. I
tried for co crystalization. Kd value of the ligand is near 40um. Any
suggestion what to do?
