Recombinant Human Frizzled-5 Fc Chimera (CHO-expressed), CF Summary

Product Specifications

Purity

>95%, by SDS-PAGE visualized with Silver Staining and quantitative densitometry by Coomassie® Blue Staining.

Endotoxin Level

<0.10 EU per 1 μg of the protein by the LAL method.

Activity

Measured by its binding ability in a functional ELISA. In a 100 µL reaction mixture containing biotinylated recombinant mouse Wnt-5a at 100 ng/mL and Recombinant Human Frizzled‑5 Fc Chimera dilutions, the concentration of Recombinant Human Frizzled‑5 Fc Chimera that produces 50% of the maximal binding response is found to be approximately 5‑20 ng/mL.
Optimal concentrations should be determined by each laboratory for each application.

Carrier Free

What does CF mean?

CF stands for Carrier Free (CF). We typically add Bovine Serum Albumin (BSA) as a carrier protein to our recombinant proteins. Adding a carrier protein enhances protein stability, increases shelf-life, and allows the recombinant protein to be stored at a more dilute concentration. The carrier free version does not contain BSA.

What formulation is right for me?

In general, we advise purchasing the recombinant protein with BSA for use in cell or tissue culture, or as an ELISA standard. In contrast, the carrier free protein is recommended for applications, in which the presence of BSA could interfere.

Background: Frizzled-5

Frizzled-5 is an approximately 62 kDa 7-TM glycoprotein that is one of at least ten Frizzled family Wnt receptors (1, 2). Wnt engagement of Frizzled, with low density lipoprotein receptor-related proteins LRP-5 or LRP-6 acting as co‑receptors, stabilizes beta -catenin and promotes gene transcription that is important in development and tissue maintenance (1). Frizzleds can also signal through non-canonical pathways independently of LRPs (1). Mature human Frizzled-5 consists of a 212 amino acid (aa) extracellular domain (ECD), a 283 aa 7-TM region, and a 64 aa cytoplasmic domain with a PDZ binding motif (2, 3). The ECD includes a cysteine-rich region (CRD) that binds Wnts and is highly conserved among Frizzled proteins (1, 2, 4). Within the N-terminal ECD, human Frizzled-5 shares 95% aa sequence identity with mouse and rat Frizzled-5. Frizzled-5 is expressed in embryonic tissues (telencephalon, pituitary, thalamus, hypothalamus, eye, liver, spleen, lung, and kidney), in the adult retina, colon, and pancreatic islets, some cancer cell lines, human embryonic stem cells, and in some monocyte and lymphocyte populations (2-8). Frizzled-5 functions as a receptor for Wnt-5a, Wnt-9b, Wnt-10b, Wnt-2b, and Wnt-7a (3, 5, 9, 10). It plays a role in the maintenance of yolk sac and placental vasculature (ishikawa) and in the regression of vitreous vasculature during eye development (5, 6, 11). It mediates the synaptogenic effect of Wnt-7a, contributes to the development of neuronal polarity, and is required for neuronal survival in the thalamus (3, 12, 13). In macrophages and monocytes, Frizzled-5 signaling induces the production of inflammatory cytokines (7, 8).
