Localization and Upregulation of the Nasal Histamine H1 Receptor in Perennial Allergic Rhinitis

Figure 2

Representative western blots for the H1 receptor protein in human nasal mucosa (lane 1: perennial allergic nasal mucosa, lane 2: nonallergic nasal mucosa). The antibody recognized a single protein of 56 kDa referred as H1 receptor. In control experiments, anti-H1 receptor antibody was preincubated with specific blocking peptides (lane 3: control for lane 1, lane 4: control for lane 2).
