Biological target:
Inhibitor of γ-secretase-mediated βAPP processing.
In vitro activity:
To investigate the effect of JLK6 on notch1 expression, cells were treated with JLK6, and a Western blot assay was performed to analyze Notch1 expression in the treated and untreated cells. According to the observations, the Notch 1 expression was significantly suppressed in the cells treated with JLK6 (figure 2f). The expression of Notch1 associated proteins including Jag5, Hes1, and Hes 1 were also significantly reduced in the samples treated with the JLK6, Notch1 inhibitor (Figure 2h). RT-qPCR showed similar results (Figure 2g-I).

Note: There can be variations in solubility for the same chemical from different vendors or different batches from the same vendor. The following factors can affect the solubility of the same chemical: solvent used for crystallization, residual solvent content, polymorphism, salt versus free form, degree of hydration, solvent temperature. Please use the solubility data as a reference only. Warming and sonication will facilitate dissolving. Still have questions? Please contact our Technical Support scientists.
