SDS-PAGE (a) and immunoblot (b and c) of cat epithelia in reducing conditions (15%T-2.67%C): Precision Plus Protein Dual Extra Standard (lane 1), NE (100 μg extract, lane 2) and CDA (100 μg, lane 3). Immunoblots were performed using serum from cat sensitized patients (b) or monoclonal antibody α-Fel d 1 (c) as primary antibody. High molecular weight SDS (d): HiMarkTM Pre-Stained HMW Protein Standard (lane 1), CDA (100 μg extract, lane 2), and NE (100 μg, lane 3)
