Serpin F1 Protein, Rat (HEK293, His)

Serpin F1 Protein, part of the secreted frizzled-related protein (sFRP) family, modulates Wnt signaling pathways. As a member, Serpin F1 likely interacts with Wnt ligands and frizzled receptors, regulating crucial cellular processes. The unique structural characteristics of Serpin F1 within the sFRP family, marked by the absence of conserved residue(s) for feature annotation propagation, underscore its distinctive role in Wnt signaling modulation. Despite lacking certain conserved elements, Serpin F1's specific attributes may contribute to its distinct influence on cellular activities, such as proliferation, differentiation, or tissue development. Serpin F1 Protein, Rat (HEK293, His) is the recombinant rat-derived Serpin F1 protein, expressed by HEK293, with C-His labeled tag. The total length of Serpin F1 Protein, Rat (HEK293, His) is 399 a.a., with molecular weight of ~45.9 kDa.

SFRP2 Protein is a member of the secreted frizzled-related protein (sFRP) family, indicating its involvement in modulating Wnt signaling pathways. As part of this family, SFRP2 likely interacts with Wnt ligands and frizzled receptors, exerting regulatory effects on crucial cellular processes. The absence of conserved residue(s) required for feature annotation propagation underscores the unique structural characteristics of SFRP2 within the sFRP family. Despite lacking certain conserved elements, SFRP2's specific attributes may contribute to its distinct role in modulating Wnt signaling, potentially influencing cellular activities such as proliferation, differentiation, or tissue development.

Measured by its ability to enhance the adhesion of Saos-2 human osteosarcoma cells to bovine Collagen I coated plate. The ED₅₀ this effect is 0.178 μg/mL, corresponding to a specific activity is 5.62×10³ units/mg.

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

Lyophilized powder

Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4 or 20 mM PB, 150 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.
