In vitro
In vitro	In vitro model of tumor heterogeneity the antitumor effects of Nigericin (NIG) that works by acting as an H⁺, K⁺, and Pb²⁺ ionophore. NIG decreased the viability and clonogenicity of H460 cells, as well as their ability to migrate and invade^[1] . Using a combination of live-cell imaging and biochemical approaches, we demonstrate that prototypical NLRP3 stimuli, the potassium ionophore nigericin, or millimolar concentrations of ATP exert both NLRP3-independent and -dependent effects on macrophages that result in cytokine release and cell death. ^[2]
Cell Research	Cell lines	H460 cells
	Concentrations	1 µM

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH₂O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
