Human Inositol Polyphosphate-4-Phosphatase Type I 107kDa (INPP4A) ELISA Kit

INPP4A (Inositol Polyphosphate-4-Phosphatase Type I, 107 kDa) is a lipid phosphatase that dephosphorylates phosphatidylinositol 3,4-bisphosphate, acting as a negative regulator of PI3K/Akt signaling. This colorimetric ELISA from Assay Genie quantifies human INPP4A protein in tissue homogenates, cell lysates, and prepared extracts, supporting research in phosphoinositide metabolism, neuronal signaling, and cancer biology. The assay is supplied as a complete microplate-based kit for research use only, with sufficient reagents for a full plate run, and the protocol accommodates small aliquots of clarified lysate prepared after standard extraction steps. Researchers commonly pair it with western blot validation and in vitro cell culture models where INPP4A expression is manipulated. Each kit includes matched vials of capture antibody, detection antibody, and recombinant standard; reagents should be kept refrigerated, protected from light, and handled in single-use aliquots to preserve activity.
