Western blot was performed using Syntaxin 6 Monoclonal Antibody (Product # MA5-14858) and a 30kDa band corresponding to Syntaxin 6 was observed in the cell line tested. Whole cell extracts (30 µg lysate) of SK-N-SH (Lane 1), SH-SY5Y (Lane 2), IMR-32 (Lane 3), HT-29 (Lane 4), Caco-2 (Lane 5), MCF-7 (Lane 6) and Mouse Brain (Lane 7) were electrophoresed using NuPAGE™ 4-12% Bis-Tris Protein Gel (Product # NP0322BOX). Resolved proteins were then transferred onto a nitrocellulose membrane (Product # LC2001) 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 SuperSignal™ West Dura Extended Duration Substrate (Product # 34076).
