I have never tried varying the order of mixing, but it seems the correct ADP-BeF3 complex was formed when mixing all three solutions just before use. Guillaume > On 22 Jun 2022, at 02:12, Firdous Tarique wrote: > > Thanks for your input. To avoid precipitation what about doing something like

Thanks for your input. To avoid precipitation what about doing something like this? For example, as we know: AlCl3 + 3NaF = AlF3 + 3NaCl Therefore, adding 100mM AlCl3 plus 300mM NaF to get 100mM of AlF3 solution, then directly using this 100 mM stock of AlF3 for the final dilution, say 1 or 2 mM

Hi Firdous, I have read a fair amount of papers about ATP-dependent chromatin remodelers in which ADP-BeF3 is often cited. It is made as follows (quoting from one of these papers): "ADP-BeF3 was prepared as a 10x stock (10 mM ADP, 30 mM BeSO4, 150 mM NaF, 10 mM MgCl2), freshly before use." So

Hi Firdous, When I have used ADP/AF3 as a transition state analogue in crystallography, I have always formed the ADP/AF3 complex in place by adding ADP, aluminum nitrate, and fluoride at a 1:1:6 ratio to my protein. I then used that mixture directly for crystallogenesis. Best, Michael From:
