HER3 Protein, Human (Biotinylated, HEK293, His-Avi)

HER3, a pivotal tyrosine-protein kinase, acts as a crucial cell receptor for neuregulins. Neuregulin-1 (NRG1) activation boosts tyrosine phosphorylation and interaction with p85 subunit of phosphatidylinositol 3-kinase. CSPG5 may also activate HER3. Its involvement in myeloid cell differentiation underscores HER3's vital role in essential cellular processes for normal development and function. HER3 Protein, Human (Biotinylated, HEK293, His-Avi) is the recombinant human-derived HER3 protein, expressed by HEK293 , with C-Avi, C-6*His labeled tag.

HER3, a tyrosine-protein kinase, serves as a critical cell surface receptor for neuregulins. Activated by neuregulin-1 (NRG1), ligand binding enhances phosphorylation on tyrosine residues and facilitates its interaction with the p85 subunit of phosphatidylinositol 3-kinase. Additionally, there is evidence suggesting activation by CSPG5. HER3 is intricately involved in the regulation of myeloid cell differentiation, highlighting its pivotal role in cellular processes crucial for normal development and function.

90-120 kDa

≥ 95%, as determined by reducing SDS-PAGE.

Lyophilized powder.

Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
