Product Information

Bioactivity

Bioactivity	Measured by its binding ability in a functional ELISA. Immobilized human ErbB4-His at 10 μg/ml (100 μl/well) can bind biotinylated human NRG1 , The EC50 of biotinylated human NRG1 is 0.4-0.92 μg/ml.
Description	ErbB4 Protein, Human, Rhesus, Recombinant (His) is expressed in HEK293 mammalian cells with His tag. The predicted molecular weight is 71.1 kDa and the accession number is Q15303-1.
Species	Human,Rhesus
Expression System	HEK293 Cells
Tag	C-His
Accession Number	Q15303-1
Construction	A DNA sequence encoding the human / rhesus ERBB4 (NP_005226.1) (Met1-Arg649) with a C-terminal polyhistidine tag was expressed. Human and Rhesus ERBB4 sequences are identical. Predicted N terminal: Gln 26
Protein Purity	≥ 85 % as determined by SDS-PAGE. ≥ 95 % 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, pH7.4. 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.
Synonyms	erb-b2 receptor tyrosine kinase 4
Research Background	ERBB4 is a single-pass type I membrane protein with multiple cysteine rich domains, a transmembrane domain, a tyrosine kinase domain, a phosphotidylinositol-3 kinase binding site and a PDZ domain binding motif. ERBB4 is expressed at highest levels in brain, heart, kidney, in addition to skeletal muscle, parathyroid, cerebellum, pituitary, spleen, testis and breast. And lower levels in thymus, lung, salivary gland, and pancreas. It specifically binds to and is activated by neuregulins, NRG-2, NRG-3, heparin-binding EGF-like growth factor, betacellulin and NTAK. ERBB4 also can be activated by other factors and induces a variety of cellular responses including mitogenesis and differentiation. ERBB4 regulates development of the heart, the central nervous system and the mammary gland, gene transcription, cell proliferation, differentiation, migration and apoptosis. It is required for normal cardiac muscle differentiation during embryonic development, and for postnatal cardiomyocyte proliferation. ERBB4 also play a role on the normal development of the embryonic central nervous system, especially for normal neural crest cell migration and normal axon guidance. It is required for mammary gland differentiation, induction of milk proteins and lactation.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.
