ERBB3, receptor tyrosine-protein kinase erbB-3, alias HER3, CD340. ERBB3 protein is a tyrosine kinase receptor belonging to the epidermal growth factor receptor family, which can form heterodimers with other EGFR family members to activate the downstream signaling pathways including PI3K/AKT and MAPK/ERK pathways, which play a critical role in cell proliferation, differentiation and survival.
ERBB3 plays a key role in a variety of normal physiological processes and in tumor development. Overexpression of ERBB3 is closely associated with the development and progression of various cancers (e.g., breast, lung, colorectal, etc.), especially in HER2-positive breast cancer. The interaction of ERBB3 with HER2 is thought to be a promoter of tumor cell proliferation and metastasis. ERBB3 is an important target for cancer therapy, and therapeutic strategies targeting ERBB3 are being widely investigated with the aim of improving patient prognosis and treatment outcomes.

Activity
Measured by its binding ability in a functional ELISA. Immobilized NRG1(CSB-MP016077HU1(F6)) at 2 μg/ml can bind human ERBB3, the EC50 is 12.32-15.74 ng/ml.
EGFR Recombinant Monoclonal Antibody (CSB-RA159341MA1HU)
Validated Data
IHC image of CSB-RA159341MA1HU diluted at 1:50 and staining in paraffin-embedded human lung cancer performed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4°C overnight. The primary is detected by a Goat anti-rabbit polymer IgG labeled by HRP and visualized using 0.05% DAB.
IHC image of CSB-RA159341MA1HU diluted at 1:50 and staining in paraffin-embedded human pancreatic tissue performed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4°C overnight. The primary is detected by a Goat anti-rabbit polymer IgG labeled by HRP and visualized using 0.05% DAB.
Overlay Peak curve showing NIH/3T3 cells stained with CSB-RA159341MA1HU (red line) at 1:100. The cells were fixed in 4% formaldehyde (15min) and permeated by 0.2% TritonX-100 for 10min. Then 10% normal goat serum to block non-specific protein-protein interactions followed by the antibody (1ug/1*106cells) for 45min at 4℃. The secondary antibody used was FITC-conjugated Goat Anti-Rabbit IgG(H+L) at 1/200 dilution for 35 min at 4°C. Isotype control antibody (green line) was mouse IgG1 (1µg/1*106cells) used under the same conditions. Acquisition of >10,000 events was performed.
