Experimental details

Western blot analysis was performed on whole cell extracts (30 µg lysate) of SH-SY5Y (Lane1), Karpus (Lane 2), MCF 7 (Lane 3) and MDA-MB 231 (Lane 4). The blots were probed with Anti-Foxo 3A Recombinant Rabbit Polyclonal Antibody (Product # 710879, 1-2 µg/mL) and detected by chemiluminescence using Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, HRP conjugate (Product # A27036, 0.4 µg/mL, 1:2500 dilution). A 82 kDa band corresponding to Foxo 3A was observed across cell lines tested. Known quantity of protein samples were electrophoresed using Novex® NuPAGE® 4-12% Bis-Tris gel (Product # NP0321BOX), XCell SureLock™ Electrophoresis System (Product # EI0002) and Novex® Sharp Pre-Stained Protein Standard (Product # LC5800). Resolved proteins were then transferred onto a nitrocellulose membrane with iBlot® Dry Blotting System (Product # IB21001). The membrane was probed with the relevant primary and secondary Antibody following blocking with 5% skimmed milk. Chemiluminescent detection was performed using Pierce™ ECL Western blotting Substrate (Product # 32106).

Experimental details

For immunofluorescence analysis, Serum starved (16 hours) SH-SY5Y cells were fixed and permeabilized for detection of Foxo3A using Foxo3A Recombinant Rabbit Polyclonal Antibody (Product # 710879, 2 µg/mL) and labeled with Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, Alexa Fluor® 488 conjugate (Product # A27034, 1:2000). Panel a) shows representative cells that were stained for detection and localization of Foxo3A protein (green), Panel b) is stained for nuclei (blue) using SlowFade® Gold Antifade Mountant with DAPI (Product # S36938). Panel c) represents cytoskeletal F-actin staining using Alexa Fluor® 555 Rhodamine Phalloidin (Product # R415, 1:300). Panel d) is a composite image of Panels a, b and c clearly demonstrating nuclear localization of Foxo3A. Panel e) shows untreated cells with cytoplasmic localization. Panel f) represents control cells with no primary antibody to assess background.
