Western blot was performed using Anti-V5 Tag Polyclonal Antibody (Product # PA1-993) by loading whole cell extracts of untransfected and transiently transfected HEK-293E lysates: untransfected, 50 µg (Lane 1), empty vector control, 50 µg (Lane 2), V5-H3-His, 50 µg (Lane 3), Myc-p65-V5, 50 µg (Lane 4), Myc-p65-V5, 25 µg (Lane 5), Myc-p65-V5, 12.5 µg (Lane 6), Myc-p65-V5, 6.26 µg (Lane 7), p65-HA, 50 µg (Lane 8) and 25 ng of Positope (Lane 9) 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). A ~65 kDa band corresponding to Myc-p65-V5 were observed in HEK293E transfected lysates on probing with the primary antibody (1 µg/mL) 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 1500 (Product # A44241). Positope (Product # R90050) is a 53 kDa recombinant protein consisting multiple epitope tags along with V5 tag, which has been used as a positive control for V5 tag detection. No cross-reactivity was seen with p65 expressing lysate.

A ~65 kDa band corresponding to Myc-p65-V5 were observed in HEK293E transfected lysates on probing with the primary antibody (1 µg/mL) and detected by chemiluminescence with Goat anti-Rabbit IgG (H+L) Superclonal™ Recombinant Secondary Antibody, HRP (Product # A27036, 1:4000 dilution) using the iBright FL 1500 (Product # A44241). Chemiluminescent detection was performed using Novex® ECL Chemiluminescent Substrate Reagent Kit (Product # WP20005). Positope (Product # R90050) is a 53 kDa recombinant protein consisting multiple epitope tags along with V5 tag, which has been used as a positive control for V5 tag detection. No cross-reactivity was seen with FLAG-tagged p65 expressing lysate.
