Subject: [Histonet] ATPase reaction


Hazel Horn asks about the ATPase reaction:

Years ago we had problem with our ATPase reaction on F/S of muscle
biopsies. We discovered that in keeping the substrate at minus 20oC in a
freezer, and getting it out and letting it warm up to room temperature
before weighing a small amount out for the procedure, and then putting
it back in the freezer,  in doing that all the time, we had
inadvertantly inactivated the ATPase substrate. Its best to aliquot it
out when you first receive it from Sigma, or whoever, and keep those
vials frozen, getting one out to use every time you do the reaction.

Other than that, I would think the solutions are suspect, too old or
wrong pH or something like that.
