I reconstituted a vial of AO's DES 1,3 IGF-1 a few days ago using 2ml of .6% AA, removed the vacuum, tilted the vial, added the diluent, and rolled gently between my hands (etc).
The IGF-1 "cake" dissolved almost instantly when the first drop of AA running down the side of the vial came in contact with it.
So my issue is that even after refrigerating the reconstituted solution for a few days, the solution still has a grainy/gritty look to it. The solution is clear, but if I look closely, I see the gritty appearance. The particles (if that is what they are) aren't white; they are clear and uniform, almost like small granules of salt.
So...is the solution usuable as is (after adding BH2O to the loaded syringe prior to pinning)? If not, any suggestions for fixing the problem (more AA, etc), or is the vial worthless?
Thanks
