The proportion of SP cells in HepG2 and HCCLM3 cell lines were 0.16% and 32.2%, which reduced to 0% and 0.28% in the presence of verapamil.
Front Pharmacol, 2018, 9:1298. Verapamil HCl purchased from Selleck.
f, Cells were pretreated with or without 5 μM verapamil and then treated with the indicated concentrations of 17-DMAG for 6 h. The proteins involved in ALK-related signaling were detected by western blot analysis.

J45.01 cells were suspended in a growth medium containing 0.1 μM 5-CFDA and kept on ice for 20 min to allow its uptake. The effects of verapamil (MDR1 inhibitor) and MK571 (MRP1 inhibitor) on the efflux of 5-CF at 37°C was determined by flow cytometry (B).

Bio Calculators
Molarity Calculator
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Dilution Calculator
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
