SFRP4 Protein, Human (HEK293, His)

The SFRP4 protein is a member of the soluble Frizzled-related protein (sFRP) and regulates Wnt signaling by directly interacting with Wnt. It has similar functions to other sFRPs and contributes to the regulation of cell growth and differentiation in specific cell types. SFRP4 Protein, Human (HEK293, His) is the recombinant human-derived SFRP4 protein, expressed by HEK293 , with C-His labeled tag. The total length of SFRP4 Protein, Human (HEK293, His) is 329 a.a., with molecular weight of 55-60 kDa.

SFRP4, a member of the soluble frizzled-related proteins (sFRPs), serves as a modulator of Wnt signaling through its direct interaction with Wnts. Demonstrating functional similarities to other sFRPs, SFRP4 contributes to the regulation of cell growth and differentiation in specific cell types. Notably, it plays a crucial role in bone morphogenesis and may act as a regulator of adult uterine morphology and function. Additionally, SFRP4 is implicated in increasing apoptosis during ovulation, potentially through the modulation of FZ1/FZ4/WNT4 signaling. Furthermore, it exhibits phosphaturic effects by specifically inhibiting sodium-dependent phosphate uptake. These diverse functions underscore the versatile regulatory role of SFRP4 in various cellular processes and physiological contexts.

Measured by its ability to inhibit Wnt3a-induced alkaline phosphatase production by C3H10T 1/2 2A6 mouse embryonal fibroblast cells and the ED₅₀ is typically 1-6 μg/mL in the presence of 20 ng/mL of Wnt3a.

55-60 kDa

Greater than 90% as determined by reducing SDS-PAGE.

Lyophilized powder.

Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween 80 are added as protectants 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.
