人類分泌性卷曲相關蛋白-1|Human sFRp-1

Synonyms :

Soluble Frizzled Related Protein-1, Secreted Apoptosis Related Protein-2, SARP-2

Description :

Secreted Frizzled Related Proteins (sFRPs) modulate WNT signaling by binding directly to WNT proteins in a manner that affects their receptor binding and signaling capabilities. sFRP-1 is a widely distributed protein that can bind directly to WNT1, WNT2, and possibly other WNT proteins, and generally exerts anti-proliferative effects consistent with activity as a WNT antagonist. It also inhibits apoptosis and has been found to be down-regulated in many solid tumors, but up-regulated in uterine leiomyomas. Recombinant human sFRP-1 is a glycosylated 283 amino acid protein containing a cysteine rich Frizzled homologous domain.

HeLa cells

Stability :

The lyophilized protein is stable for at least 2 years from date of receipt at -20⁰C. Reconstituted sFRP-1 is stable for at least 3 months when stored in working aliquots with a carrier protein at -20⁰C. Avoid repeated freeze/thaw cycles.

Purity :

Greater than 97% by SDS-PAGE gel and HPLC analyses.

Endotoxin Level :

Endotoxin level is less than 0.1 ng per μg (1EU/μg).

Biological Activity :

Determined by its ability to inhibit BMP-2 proliferation effect of ATDC-5 cells. The expected ED₅₀ is 0.3–0.5 μg/ml.
