D-myo-Inositol-1,3,4,5,6-pentaphosphate (ammonium salt) can bind to the PH domain of Grp1 with a Kd of 590 nM. D-myo-Inositol-1,3,4,5,6-pentaphosphate (ammonium salt) can inhibit the phosphorylation and kinase activity of Akt/PKB, inducing apoptosis in ovarian, lung, and breast cancer cells. D-myo-Inositol-1,3,4,5,6-pentaphosphate (ammonium salt) exhibits antiangiogenic activity in vitro and blocks capillary tube formation of HUVEC. D-myo-Inositol-1,3,4,5,6-pentaphosphate (ammonium salt) exerts antitumor effects against cancer xenografts in nude mice.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C.
