  • (C,D) The Ba/F3 cells expressing EGFR-T854A/C797S/del19 (C) and EGFR-T854A/C797S/L858R (D) were treated with gefitinib, afatinib, osimertinib, and brigatinib for 6 hours at indicated concentrations. EGFR phosphorylation and downstream signal pathway were evaluated by Western blotting.

    F, PC-9/ffluc and PC-9/LMC-GR cells (2×103 cells/well) were incubated with various concentrations of osimertinib for 72 hours. Cell viability was determined by MTT assay. Bars represent SD of quadruplicate cultures. Data shown are representative of three independent experiments with similar results.

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.
