WIF-1 蛋白, Human (HEK293, His)

WIF-1 protein critically binds to WNT protein, inhibits its activity and regulates the WNT signaling pathway. In addition to its inhibitory role, WIF-1 may also contribute to mesoderm segmentation, implicating its role in embryonic development. WIF-1 Protein, Human (HEK293, His) is the recombinant human-derived WIF-1 protein, expressed by HEK293 , with C-6*His labeled tag. The total length of WIF-1 Protein, Human (HEK293, His) is 351 a.a., with molecular weight of ~45.0 kDa.

WIF-1 蛋白发挥着至关重要的作用，因为它与 WNT 蛋白结合，有效抑制其活性。这种相互作用表明 WNT 信号通路具有关键的调节功能。除了其抑制作用外，WIF-1 还可能参与中胚层分割，暗示其对胚胎发育的潜在贡献。此外，WIF-1 与 MYOC 相互作用，表明可能与其他细胞过程或信号级联有关。WIF-1 的多方面相互作用强调了其在调节 WNT 介导的活动中的重要性及其在更广泛的发育和细胞事件中的潜在参与。

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

无菌粉末.

Lyophilized from a 0.2 μm filtered solution of 10 mM HAc-NaAc, 150 mM NaCl, 0.5% CHAPS, pH 4.0 or 50 mM Tris-HCL, 300 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.
