Dye Reagents

[Target]

ABCA1[1], VDAC1[2].

[In Vitro]

Concentration less than 400 μM DIDS has no evident cytotoxic effect on cell viability Pre-treatment with DIDS at the concentration of 100 and 200 μM result in a prevented effect on ALA-SDT-induced cell death, while dose at 50 μM has no inhibition effect. At the concentration of 400 μM DIDS itself slightly decreases the cell viability, although there is no significant statistic difference as compared with the untreated control. Pre-treatment with DIDS (100 μM) clearly inhibit caspase-3 and caspase-9 activation[2].

[Cell Assay]

Cells (5×105 cells/mL) are seeded in the 35-mm Petri dishes and cultured for 72 h at 37°C. Cells are pre-incubated with ALA, and then DIDS of diverse concentrations (0-200 μM) is added before exposed to ultrasound. Cell apoptosis is detected. Briefly, seeded cells (5×105 cells/mL) are pre-treated with test compounds at the indicated concentrations for 1 h (DIDS and NAC), 1.5 h (BAPTA) or with siRNA and exposed to ultrasound. Six hours after ALA-SDT treatment, cells are collected[2].
