    In Vitro

    U-46619 (1 nM-10 μM) causes platelets shape change and aggregation in a concentration-dependent manner, and with EC50s of 0.58 μM and 0.013 μM for aggregation and shape change, respectively[1].
    U-46619 (10 nM-10 μM) increases internal Ca2+ concentration ([Ca2+]i) and activates phosphoinositide (PI) hydrolysis in a concentration-dependent manner with a similar concentration-dependency[1].
    U-46619 (3 nM-10 μM) also activates GTPase concentration-dependently in the membranes derived from platelets[1].
    U-46619 improves the differentiation efficiency of human induced pluripotent stem cells into endothelial cells by activating both p38MAPK and ERK1/2 signaling pathways[2].

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
