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).

Product Summary for Human Total ErbB4/Her4 DuoSet IC ELISA
This DuoSet IC ELISA contains the basic components required for the development of sandwich ELISAs to measure total ErbB4 / Her4 in cell lysates. An immobilized capture antibody specific for ErbB4 / Her4 binds both phosphorylated and unphosphorylated ErbB4 / Her4. After washing away unbound material, a biotinylated detection antibody is used to detect both phosphorylated and unphosphorylated protein, utilizing a standard Streptavidin-HRP format.

Standard Curve
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 # HAF008) 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.
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 μg of lysate.Kit Contents for Human Total ErbB4/Her4 DuoSet IC ELISA
