Western blot was performed using Anti-G6PD Rabbit Polyclonal Antibody (Product # PA5-29662) and a 59 kDa band corresponding to G6PD was observed across cell lines and tissues tested except Mouse Testis and Mouse Heart. Whole cell extracts (30 µg lysate) of A549 (Lane 1), HCT 116 (Lane 2), SW480 (Lane 2), MCF7 (Lane 4), HeLa (Lane 5), 3T3-L1 (Lane 6), 3T3-L1 differentiated to Adipocytes (Lane 7), K-562 (Lane 8), Mouse Adipose (Lane 9), Mouse Testis (Lane 10) and Mouse Heart (Lane 11) were electrophoresed using NuPAGE™ 4-12% Bis-Tris Protein Gel (Product # NP0322BOX). Resolved proteins were then transferred onto a nitrocellulose membrane (Product # IB23001) by iBlot® 2 Dry Blotting System (Product # IB21001). The blot was probed with the primary antibody (1:1000 dilution) and detected by chemiluminescence with Goat anti-Rabbit IgG (Heavy Chain), Superclonal™ Recombinant Secondary Antibody, HRP (Product # A27036, 1:4000 dilution) using the iBright FL 1000 (Product # A32752). Chemiluminescent detection was performed using Novex® ECL Chemiluminescent Substrate Reagent Kit (Product # WP20005).
