ActoFactor™ Recombinant Human Secreted frizzled-related protein 1

  • Specification
  • Recommended Products
Cat.No.
CSC-CTK0438
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.
Species
Human
Product Overview
Human SFRP1 expressed in HeLa cells
Molecular Mass
N/A
Size
CAT# CSC-CTK0438-20 (20 μg); CAT# CSC-CTK0438-100 (100 μg)
Expression System
HeLa cells
Purity
Greater than 97% as determined by SDS-PAGE and HPLC analysis.
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.
Endotoxin Level
Less than 1 EU/μg.
Formulation
Lyophilized from a sterile-filtered solution with no additives.
Reconstitution
Please centrifuge product before opening vial. The lyophilized protein should be reconstituted with distilled, sterile water to a concentration of 0.1-1.0 mg/ml. For further dilution, carrier protein (0.1% BSA or HSA) should be added to avoid loss of bioactivity.
Storage & Stability
The lyophilized protein, though stable at room temperature for up to 3 weeks, is best stored desiccated at -20°C. Reconstituted protein should be used immediately or stored long-term in undiluted working aliquots at -20°C. For long-term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Avoid repeated freeze-thaw cycles.
