Analysis of Bax, Bcl-2 and caspase-3 protein was performed using the ELISA method. The MCF-7 cells (2 × 104/well) were seeded into 96-well plate. The cells were treated with free AZA, AZA-LPO and blank liposome samples for 24 h. Thereafter, the wells were incubated with monoclonal antibodies against Bax (Ab-1) (DRG® Human Bax ELISA Kit), Bcl-2 (Zymed® Bcl-2 ELISA Kit) and caspase-3 (Invitrogen ELISA kit). The procedure was followed as per manufacturer instruction [49 (link)].
