Figure 3From: Analysis of EGFR signaling pathway in nasopharyngeal carcinoma cells by quantitative phosphoproteomics Validation of EGFR-regulated phosphoproteins by IP-Western blotting. A, IP-Western blotting analysis showing that EGF induces phosphorylation of three identified proteins (ANXA3, KRT8 and KRT18). Try, anti-phosphotyrosine antibody B, IP-Western blotting analysis showing that phospho-EGFR interacts with GSTP1 and GRB2. CBB gel staining serves as loading control (IgG heavy chain).Back to article page
