D-myo-Inositol-1,2,4,5-tetraphosphate (Ins(1,2,4,5)P4) is one of the many inositol phosphate (InsP) isomers that act as small, soluble second messengers in the transmission of cellular signals.1,2,3 Ins(1,2,4,5)P4 exhibits agonist activity at the Ins(1,4,5)P3 receptor expressed in CHO cells where it induces Ca2+ mobilization with an ED50 value of 0.22 µM, making it nearly equipotent to Ins(1,4,5)P3 (EC50 = 0.1 µM) in the same assay.4WARNING This product is not for human or veterinary use.
