Formulation, Preparation, and Storage

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.

Carrier: 7584-SF
Formulation Lyophilized from a 0.2 μm filtered solution in NaH2PO4 and NaCl with BSA as a carrier protein.
Reconstitution Reconstitute at 250 μg/mL in PBS containing at least 0.1% human or bovine serum albumin.

Background: sFRP-3

Secreted Frizzled Related Protein‑3 (sFRP‑3), also known as FRZB, belongs to a family of Wnt-binding proteins with homology to the ligand‑binding domain of the Frizzled receptors. sFRPs are approximately 30‑35 kDa in size and contain an N‑terminal Frizzled‑like domain with 10 conserved cysteines and a Netrin-like C‑terminal domain (1‑4). Mature human sFRP‑3 shares 93% aa sequence identity with mouse and rat sFRP‑3. It neutralizes the bioactivity of Wnt‑1, ‑5a, ‑9a, Xenopus Xwnt‑8, and EGF (5‑8). sFRP‑3 regulates somitic myogenesis and osteoblast differentiation as well as morphogenesis of the cochlear epithelium, hair follicle, and cardiac atrioventricular cushion (6, 8‑10). sFRP‑3 also functions as a tumor suppressor in a variety of cancers including melanoma, medulloblastoma, soft tissue sarcoma, and androgen‑independent prostate cancer. It inhibits epithelial-mesenchymal transition, tumor growth and invasion, and the activity of MMP‑2 and MMP‑9 (7, 11‑13). In contrast, it can promote tumor growth and angiogenesis in renal cancer (14).
