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.


Formulation Lyophilized from a 0.2 μm filtered solution in PBS and NaCl with Trehalose. 
Reconstitution Reconstitute at 200 μg/mL in PBS.
Shipping The product is shipped at ambient temperature. Upon receipt, store it immediately at the temperature recommended below.
Stability & Storage: Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
  • 12 months from date of receipt, -20 to -70 °C as supplied.
  • 1 month, 2 to 8 °C under sterile conditions after reconstitution.
  • 3 months, -20 to -70 °C under sterile conditions after reconstitution.

Background: sFRP-5

Secreted Frizzled Related Protein‑5 (sFRP‑5), also known as SARP‑3, 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 (1‑3). Mature mouse sFRP‑5 shares 96% and 99% aa sequence identity with human and rat sFRP‑2, respectively (4). During embryonic development, sFRP‑5 is expressed in the anterior visceral endoderm, neural tube, foregut epithelium, and proliferating and prehypertrophic chondrocytes (5‑8). sFRP‑5 activity is required for the development of foregut, liver, ventral pancreas, and somites (6, 7). In the adult, sFRP‑5 is expressed in the retinal pigment epithelium and pancreas (4, 9). sFRP‑5 binds and antagonizes the function of mammalian Wnt‑5a and Wnt‑11 as well as Xenopus Xwnt‑8, resulting in an inhibition of both canonical and non‑canonical Wnt signaling (4, 7, 10). sFRP‑5 down‑regulation is common in breast and gastric cancer cells and is correlated with poor prognosis (11‑13). It functions as a tumor suppressor by inhibiting epithelial‑mesenchymal transition, invasiveness, and tumorigenicity of ovarian cancer cells (14). sFRP‑5 plays an important role in maintaining glucose handling and insulin sensitivity (10). It is secreted by adipocytes and is down‑regulated in mouse models of obesity and type 2 diabetes (10).
