HER3 蛋白, Human (312a.a, HEK293, Fc)

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 (312a.a, HEK293, Fc) is the recombinant human-derived HER3 protein, expressed by HEK293 , with C-hFc labeled tag.

HER3 是一种酪氨酸蛋白激酶，是神经调节蛋白的关键细胞表面受体。由神经调节蛋白-1 (NRG1) 激活，配体结合增强酪氨酸残基的磷酸化，并促进其与磷脂酰肌醇 3-激酶 p85 亚基的相互作用。此外，有证据表明 CSPG5 可以激活。HER3 错综复杂地参与骨髓细胞分化的调节，突出了其在对正常发育和功能至关重要的细胞过程中的关键作用。

The enzyme activity of this recombinant protein is testing in progress, we cannot offer a guarantee yet.

Approximately 69 kDa

Greater than 95% as determined by reducing SDS-PAGE.

无菌粉末.

Lyophilized from a 0.2 μm filtered solution of 20 mM PB, 150 mM NaCl, 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. 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.
