Animal-Free FGF-13 蛋白, Human (His)

FGF-13 protein is a microtubule-binding protein that directly binds and stabilizes tubulin and affects microtubule polymerization. It exerts negative regulation on axonal and leading process branches, which are critical for neuronal polarization and migration in the cerebral cortex and hippocampus. Animal-Free FGF-13 Protein, Human (His) is the recombinant human-derived animal-FreeFGF-13 protein, expressed by E. coli , with C-His labeled tag. The total length of Animal-Free FGF-13 Protein, Human (His) is 245 a.a., with molecular weight of ~21.23 kDa.

FGF-13 是一种微管结合蛋白，与微管蛋白直接相互作用，参与微管的聚合和稳定。这种微管动力学的参与表明，通过负向调节轴突和主导过程的分支，在轴突的细化中发挥作用。此外，FGF-13 在大脑皮层和海马内神经元的极化和迁移中起着至关重要的作用。它进一步调节电压门控钠通道的转运和功能，影响特定钠通道亚型的活性。除了与微管相关的功能外，FGF-13 还参与吊灯神经元促进的轴突起始段靶向抑制性 GABA 能突触的发育。通过其多样化的相互作用，包括与各种钠通道和 MAPK 信号传导成分的相互作用，FGF-13 在控制神经元过程和突触功能的复杂调节网络中发挥着多方面的作用。

Approximately 21.23 kDa

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

无菌粉末.

Lyophilized from a solution containing 1X PBS, pH 7.4, trehalose.

<0.1 EU per 1 μg of the protein by the 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.
