- Western blot was performed using Anti-Carbonic Anhydrase IX Polyclonal Antibody (Product # PA1-16592) and ~ 50-55 kDa bands corresponding to CA9 was observed across cell lines tested and increased upon Deferoxamine and Cobalt Chloride treatment in HeLa along with an uncharacterized band (*) at ~35 kDa. Whole cell extracts (30 µg lysate) of U-87 MG (Lane 1), HeLa (Lane 2), HeLa treated with Deferoxamine (100uM for 24 Hours) (Lane 3) and HeLa treated with Cobalt Chloride (200uM for 24 Hours) (Lane 4) were electrophoresed using NuPAGE® 4-12 % Bis-Tris 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 (0.5ug/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 1000 (Product # A32752). Chemiluminescent detection was performed using Novex® ECL Chemiluminescent Substrate Reagent Kit (Product # WP20005).

- Immunohistochemical analysis of Carbonic Anhydrase IX in formalin-fixed paraffin-embedded tissue section of human breast cancer. Samples were incubated in Carbonic Anhydrase IX polyclonal antibody (Product # PA1-16592) using a dilution of 1:1000 followed by HRP labeled secondary antibody and DAB reagent. Nuclei of the cells were counterstained with hematoxylin. This CAIX antibody generated an expected cytoplasmic staining of CAIX protein with an intense signal around the cellular membranes in tumor cores. The latter are more likely to be hypoxic in growing tumors which signifies that the observed CAIX staining is specific.
