Cellular toxicity of the endocytic inhibitors in the presence of P/G/L nanoparticles in Sf 1 Ep cells. Combined cellular toxicity of P/12-7NH-12/L or P/12-7NGK-12/L in the presence of chemical inhibitors/potassium free buffer in Sf 1 Ep cells was measured at 72 hours. Filipin had a significantly high combined toxicity; therefore, it was not selected for gene expression study of the P/12-7NGK-12/L nanoparticles.
