Figure 6From: SiO2 nanoparticles induce cytotoxicity and protein expression alteration in HaCaT cellsA representative 2D-DIGE image of the whole lysate of HaCaT cells exposed to 15-nm, 30-nm or micro-sized SiO 2 particles at 10 μg/mL. The denoted protein spots were those altered by SiO2 exposure and identified by MS. The differentially expressed proteins were quantitatively analyzed and were listed in Table 2 along with protein identifiers.Back to article page
