Product Information

Bioactivity

Bioactivity	Measured by its binding ability in a functional ELISA.1. Immobilized mouse ErbB3-His 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 mouse ErbB3-His at 10 μg/ml (100 μl/well) can bind biotinylated human NRG1 (aa 2-246)-Fc with a linear range of 6.25-100 ng/ml.
Description	HER3/ERBB3 Protein, Mouse, Recombinant (His) is expressed in HEK293 mammalian cells with His tag. The predicted molecular weight is 70 kDa and the accession number is Q61526.
Species	Mouse
Expression System	HEK293 Cells
Tag	C-His
Accession Number	Q61526
Construction	A DNA sequence encoding the mouse ERBB3 (Q61526) extracellular domain (Met 1-His 641) was expressed, with a C-terminal polyhistidine tag. Predicted N terminal: Ser 20
Protein Purity	> 93 % as determined by SDS-PAGE.≥ 90 % as determined by SEC-HPLC. ,
Endotoxin	< 1.0 EU/μg of the protein as determined by the LAL method.
Formulation	Lyophilized from a solution filtered through a 0.22 μm filter, containing PBS, pH 7.4. Typically, a mixture containing 5% to 8% trehalose, mannitol, and 0.01% Tween 80 is incorporated as a protective agent before lyophilization.
Reconstitution	Reconstituted with sterile deionized water to 0.25 mg/mL. Reconstitution conditions may vary depending on the lot.

Research Background	ErbB3, also known as Her3(human epidermal growth factor receptor3), is a member of the epidermal growth factor receptor (EGFR) family of receptor tyrosine kinases. This membrane-bound glycoprotein has a neuregulin binding domain but has not an active kinase domain., and therefore can not mediate the intracellular signal transduction through protein phosphorylation. However, its heterodimer with ErbB2 or other EGFR members responsible for tyrosine phosphorylation forms a receptor complex with high affinity, and initiates the related pathway which lead to cell proliferation or differentiation. ErbB3 has been shown to implicated in numerous cancers, including prostate, bladder, and breast tumors. This protein has different isoforms derived from alternative splicing variants, and among which, the secreted isoform lacking the intermembrane region modulates the activity of membrane-bound form.Cancer ImmunotherapyImmune CheckpointImmunotherapyTargeted Therapy

Storage & Solubility Information

Shipping	In general, lyophilized powders are shipped with blue ice, while solutions are shipped with dry ice.
Storage	It is recommended to store recombinant proteins at -20°C to -80°C for future use. Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at -80°C. For reconstituted protein solutions, the solution can be stored at -20°C to -80°C for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots.
