[ccp4bb] Summary of : Dissolving Hydrophobic ligands for co-crystallization and assays

2010-05-17 Thread Tuhin Bhowmick
Dear friends, here I'm summarizing all of your suggestions regarding dissolving a hydrophobic ligand (in this case, containig benzoic acid moities) for crystallization and biochemical assays: 1)Sodium salts of benzoic acid containing molecules can often be soluble in water to high

[ccp4bb] Dissolving Hydrophobic ligands for co-crystallization and assays

2010-05-13 Thread Tuhin Bhowmick
Dear All, does anyone have any clever suggestion/s for handling the solubility problem of highly hydrophobic compound, during co-crystallization or inhibition assays? The ligands I am using are almost insoluble in aquous medium (precipitates out or becomes turbid at ~1 micro molar conc.). In

[ccp4bb] aspherical atom refinement against F and F^2

2007-07-17 Thread Tuhin Bhowmick
Dear all: I am working on the aspherical atom refinement of a small molecule using the XD package. The program provides you with the option of selecting a refinement strategy against F or F^2. I have noticed that the R-factors and GOFs calculated based on F^2 are larger in magnitude compared to
