  Figure 2: Spectral Confocal Microscopy of CHO cells using GM-1E7 antibody. CHO cells were transiently transfected with an expression vector encoding IL13-R. Binding of GM-1E7 was visualized with a FITC-conjugated secondary antibody (green). Actin filaments are labeled with Alexa Fluor-555 Phalloidin (Red). Cell nuclei are stained with DAPI (Blue).

  Figure 1: FACS analysis of BOSC23 cells using GM-1E7 antibody. BOSC23 cells were transiently transfected with an expression vector encodingeither IL13-R (Red curve) or an irrelevant protein (control transfectant: black curve). Binding of GM-1E7 was detected with a PE-conjugated secondary antibody. A positive signal was obtained only with IL13-R transfected cells.

  Figure 3: Antagonistic Properties of GM-1E7 Dose-dependent inhibition of cellular proliferation. Samples of TF-1 cells were incubated for 72 h with 10 nM human IL-13 (closed circles) or 10 nM Human IL-4 (open circles) plus the indicated concentrations of purified GM-1E7. Antibody GM1E7 blocks IL-13-dependent cell proliferation completely, but only marginally influences IL-4-activity on TF-1 cells.

• Background: Interleukin 13 (IL-13) is a T cell derived cytokine involved in the regulation of inflammatory and im-mune responses. IL-13Ra1 together with IL-4Ra forms a functional receptor for both IL-4 and IL-13, which is why these two cytokines share many of their biological activities. The receptor is found on human B cells, monocytes and endothelial cells. However, no functional receptor is expressed on T cells, which explains why IL-13, in contrast to IL-4, fails to induce TH2-cell differentiation
• Synonyms: Interleukin-13 receptor alpha-1 chain, IL-13R-alpha-1, IL-13RA-1, IL13R, IL13RA, IL13 receptor alpha, CT19
• Note: SDS-PAGE analysis: The antibody was purified by Protein G Affinity Chromatography from cell culture supernatants and verified by SDS-Page (Figure.4).
