Work with LifeSpan to design a custom immunohistochemistry to address your specific biological question. Outsource the entire localization process without having to
worry about finding and characterizing target specific antibodies, sourcing and validating difficult-to-find tissues, and having the ability to interpret the resulting
immunostaining in relation to complex human pathologies.
TCR Screening Services
Test your therapeutic antibodies in immunohistochemistry against a broad panel of normal frozen human tissue types in order to determine potential unintended binding.
Our non-GLP TCR services are designed on the FDA recommendation outlined in their "Points to Consider in the Manufacture and Testing of Monoclonal Antibody Products for Human Use".
Measured by its binding ability in a functional ELISA. 1. Immobilized rat ERBB3-Fc at 10 µg/ml (100 µl/well) can bind biotinylated human NRG1 (isoform Beta1) with a linear range of 0.018-0.125 µg/ml. 2. Immobilized rat ERBB3-Fc at 10 µg/ml (100 µl/well) can bind biotinylated human NRG1 (aa 2-246)-Fc with a linear range of 0.018-0.25 µg/ml.

ERBB3 / HER3 is a member of the epidermal growth factor receptor (EGFR) family of receptor tyrosine kinases. This membrane-bound protein has a neuregulin binding domain but not an active kinase domain. It therefore can bind this ligand but not convey the signal into the cell through protein phosphorylation. However, it does form heterodimers with other EGF receptor family members which do have kinase activity.
