Afamin/AFM Protein, Human (587a.a, HEK293, His)

Afamin/AFM protein serves as a carrier of hydrophobic molecules in body fluids and plays an important role in the solubility and activity of lipidated Wnt family members (including WNT1, WNT2B, WNT3, WNT3A, WNT5A, WNT7A, WNT7B, WNT8, WNT9A, and WNT9B). The role of WNT10A and WNT10B. It also binds to vitamin E and may act as a transporter of this vitamin in body fluids, especially when the lipoprotein system is deficient. Afamin/AFM Protein, Human (578a.a, HEK293, His) is the recombinant human-derived Afamin/AFM protein, expressed by HEK293 , with C-10*His labeled tag.

Afamin/AFM protein acts as a carrier for hydrophobic molecules in body fluids, potentially playing a crucial role in the solubility and activity of lipidated Wnt family members, including WNT1, WNT2B, WNT3, WNT3A, WNT5A, WNT7A, WNT7B, WNT8, WNT9A, WNT9B, WNT10A, and WNT10B. Additionally, it binds vitamin E and may function as a transporter for this vitamin in body fluids, particularly under conditions where the lipoprotein system is insufficient. There is a potential involvement in the transport of vitamin E across the blood-brain barrier. Afamin forms a 1:1 complex with Wnt family members, interacting with a range of WNT proteins, including WNT1, WNT2B, WNT3, WNT3A, WNT5A, WNT7A, WNT7B, WNT8, WNT9A, WNT9B, WNT10A, and WNT10B.

Measured by its ability to chemoattract bioassay using MC3T3-E1 cells. The ED₅₀ for this effect is 15.01ng/mL, corresponding to a specific activity is 4.657×10⁴ units/mg.

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

Lyophilized powder.

Lyophilized from a 0.2 μm filtered solution of 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.
