TrkA 蛋白, Canine (HEK293, His)

TrkA Protein (isoform 3) belongs to the nerve growth factor receptor family and can promote angiogenesis and has carcinogenic activity when overexpressed. TrkA Protein (isoform 3) antagonizes the anti-proliferative NGF-NTRK1 signaling that promotes the differentiation of neuronal precursors. TrkA Protein, Canine (HEK293, His) is the recombinant canine-derived TrkA protein, expressed by HEK293 , with N-His labeled tag.

TrkA Protein (isoform 3) 仅在未分化的早期神经祖细胞、人类神经母细胞瘤 (NBs) 和其他神经嵴源性肿瘤的亚群中表达，能促进血管生成，并在过度表达时具有致癌活性。TrkA Protein (isoform 3) 拮抗促进神经元前体分化的抗增殖性 NGF-NTRK1 信号^[1]。

Measured by its ability to inhibit NGF-induced proliferation of TF-1 human erythroleukemic cells. The ED₅₀ for this effect is 1.122 μg/mL in the presence of 10 ng/mL of NGF (HY-P7660), corresponding to a specific activity is 891.2656 U/mg.

无菌粉末

Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4, 5% trehalose, 5% mannitol and 0.01% Tween80.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O.

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.
