Data Examples
Figure 1: The Human Total ErbB4 DuoSet IC ELISA is more sensitive than Western blot analysis. Lysates prepared from MDA-MB-453 human breast cancer cells were serially diluted and analyzed by (A) Western Blot and (B) this DuoSet® IC ELISA. Immunoblots were incubated with an anti-ErbB4 polyclonal antibody to detect total ErbB4. Bands were visualized with anti-rabbit IgG-HRP (Catalog # ) followed by chemiluminescent detection. Human ErbB4 can be detected in this DuoSet® IC ELISA by using approximately 5 to 10 times less lysate than is needed for a conventional IP-Western Blot. |
Figure 2: The Human Total ErbB4 DuoSet IC ELISA measures the relative level of ErbB4. Lysates were prepared from MDA-MB-453 human breast cancer cells and the MCF-7 human breast cancer cell line. Both ELISA and Western Blot (inset) analyses were performed using 100 g of lysate. The Western Blot was performed as described in Figure 1. |

Background: ErbB4/Her4
ErbB4, also known as Her4, is a type I membrane glycoprotein that is a member of the ErbB family of tyrosine kinase receptors. ErbB family members serve as receptors for the EGF family of growth factors. ErbB4 ligands include the neuregulins, betacellulin and heparin-binding EGF-like growth factor (HB-EGF).
