Carrier Free
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.
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.

Reconstitution Calculator
Background: PRDC/GREM2
PRDC/GREM2 (Protein Related to DAN and Cerberus/Gremlin-2) is a secreted BMP antagonist belonging to the Cerberus/DAN (CAN) family. Similar to other CAN family members, PRDC/GREM2 has 6 conserved cysteine residues that form a cysteine knot, and two additional cysteine residues located in the loops of the cysteine knot (1-3). Mature human PRDC/GREM2 is synthesized as a 168 amino acid (aa) monomer. At the amino acid level, mature human PRDC/GREM2 shares 97% sequence identity with mature mouse PRDC/GREM2. PRDC/GREM2 is biologically active as a homodimer that assembles its subunits in a head-to-tail orientation. PRDC/GREM2 is up-regulated through Wnt/ beta -catenin signaling and has been shown to potently inhibit BMP-2, -4, and -7 (4-6). During early development PRDC/GREM2 is involved in tooth morphogenesis, osteogenesis, and neurogenesis (7-9). In the adult, PRDC/GREM2 is involved in bone repair and bone remodeling (10). PRDC/GREM2 has been detected in the adult ovary, brain, spleen, and colon (11). The biological activity of PRDC/GREM2 can be blocked by binding to heparin (4).
