Semaphorin-3A/SEMA3A 蛋白, Mouse (HEK293, His)

Semaphorin-3A/SEMA3A Protein guides growth cones and is implicated in sensory projection patterning, selectively repelling axons that terminate dorsally. It contributes to olfactory system development and neuronal control of puberty. SEMA3A interacts with PXND1, although the exact nature of this interaction is unspecified. Semaphorin-3A/SEMA3A Protein, Mouse (HEK293, His) is the recombinant mouse-derived Semaphorin-3A/SEMA3A protein, expressed by HEK293, with N-His labeled tag. The total length of Semaphorin-3A/SEMA3A Protein, Mouse (HEK293, His) is 752 a.a., with molecular weight of ~86.6 kDa.

Semaphorin-3A/SEMA3A 蛋白在引导生长锥中发挥着至关重要的作用。据信，它通过选择性地排斥通常终止于背侧的轴突来参与感觉投射的模式化。SEMA3A 还参与嗅觉系统的发育，并有助于青春期的神经元控制。此外，它与 PXND1 相互作用，尽管这种相互作用的确切性质尚未明确。

无菌粉末.

Lyophilized from a 0.2 μm filtered solution of 20 mM Tris, 150 mM NaCl, 100 mM L-Arginine, 100 mM glutamic acid, pH 8.5. Normally 8% trehalose is added as protectant before lyophilization.

<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.
