Tenascin/Tnc 蛋白, Human (HEK293, His)

TNC proteins guide neuronal and axonal migration and contribute to development, synaptic plasticity, and neuronal regeneration. Tenascin/Tnc protein, Human (HEK293, His) is the recombinant human-derived Tenascin/Tnc protein, expressed by HEK293 , with C-His labeled tag. The total length of Tenascin/Tnc protein, Human (HEK293, His) is 599 a.a., with molecular weight of 66-70 kDa.

TNC 蛋白是一种细胞外基质蛋白，在发育过程中引导神经元和轴突迁移方面发挥着至关重要的作用，有助于突触可塑性和神经元再生等过程。它促进单层星形胶质细胞上生长的皮层神经元的神经突生长，表明它参与神经系统内复杂的细胞相互作用。作为整合素 α-8/β-1、α-9/β-1、α-V/β-3 和 α-V/β-6 的配体，TNC 建立了细胞通讯和信号传导所必需的分子连接。在肿瘤中，TNC 通过促进内皮细胞的伸长、迁移和萌芽来刺激血管生成。在结构上，TNC 以同源六聚体形式存在，在三卷曲螺旋区域可能形成同源三聚体，并通过两端的二硫环进一步稳定。这种多功能蛋白质还与 CSPG4 相互作用，表明它参与不同生物背景下的多种细胞和分子过程。

Measured by the ability of the immobilized protein to block Fibronectin-mediated adhesion of NIH-3T3 mouse embryonic fibroblast cells. Tenascin immobilized at 15 μg/mL, in the presence of 0.1 μg/mL human Fibronectin, will block approximately 72.51% NIH-3T3 cell adhesion (5×10⁴ cells/well, 100 μL/well).

Approximately 53-80 kDa due to the glycosylation.

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

无菌粉末

Lyophilized from a 0.22 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. 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.
