problem with ATP - (Apr/16/2014 )
Hi everybody !!!
first of all I want to apologize for my English.
My Problem: I want to measure the PMCA activity. To do that I need free ATP, and I have ATP + Ba or ATP + Na- . The original technique used a cation exchange column with dowex 50 as resin. I dont have this resin. Do you now another resin with the similar characteristics? An
Thanks a lot for you help!!!
Have a good day
are you sure you need the free acid? the dowex was probably used just to remove barium.
i would think that the sodium salt would suffice. once you add it to the solution, the atp will exchange the sodium with calcium.
