Product Datasheets

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: WISP-1/CCN4

Human WISP-1 (Wnt-induced secreted protein-1; also CNN4) is a 40 kDa, secreted, heparin-binding glycoprotein that is a member of the CCN (or CTGF/Cyr61/Nov) cysteine-rich protein family (1-5).  It is synthesized as a 367 aa precursor that contains a series of structural homology modules.  Following a 22 amino acid (aa) signal sequence, there is a 68 aa IGFBP-like domain (aa 53-120), a 57 aa von Willebrand factor type C (VWC) module (aa 126-182), a 40 aa TSP type I domain (aa 220-259) and a 75 aa, C-terminal cysteine knot motif (aa 273-347).  The VWC module is associated with protein-protein interaction, the TSP domain binds sulfated glycoconjugates, and the cysteine knot mediates dimerization and receptor binding (4).  It is likely that WISP-1 normally circulates as an 80 kDa homodimer (2).  At least five alternative splice forms are known for WISP-1.  One is 30 kDa in size, 258 aa in length, and shows a substitution of a His for aa 95-182.  This removes the VWC domain (2, 6).  A second isoform is 155 aa in length and shows a frameshift at Arg 117 with a unique 38 aa C-terminal extension.  A third is 195 aa in length and shows a 31 aa substitution for the first 203 aa of the full length precursor (6).  This retains the VWC and cysteine knot domains.  A fourth shows a 43 aa substitution for aa 117-367 for a total length of 163 aa.  This effectively removes everything but the IGFBP-like domain (7).  The last splice form contains a deletion of aa 25-269 for a total length of 122 aa.  Thus, only the signal sequence and cysteine knot motifs are retained (8).  This leaves only the IGFBP-like domain (9).  Full-length mature human WISP-1 is 85% aa identical to both mouse and rat WISP-1.  WISP-1 is expressed by osteoblasts and may contribute to fracture healing by promoting bone cell formation (10, 11).
