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.
Reconstitution Reconstitute at 300 μg/mL in sterile 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.

Background: Decorin

Decorin, also known as PG40 and PGS2, is a secreted chondroitin/dermatan sulfate proteoglycan in the family of small leucine‑rich proteoglycans (SLRPs). SLRP family members are characterized by N‑terminal and C‑terminal cysteine‑rich regions which flank the central region containing 10 ‑ 12 tandem leucine‑rich repeats (LRR) (1). The human Decorin cDNA encodes a 359 amino acid (aa) precursor that includes a 16 aa signal sequence and a 14 aa propeptide (2). Mature human Decorin contains twelve tandem LRR and shares 80% and 78% aa sequence identity with mouse and rat Decorin, respectively. Alternate splicing of human Decorin generates five isoforms with variable length deletions. Decorin is an N‑glycosylated protein that also carries a variably‑sized hybrid chondroitin/dermatan sulfate chain at Ser34 (3, 4). Naturally occurring Decorin proteoglycan has a molecular mass of approximately 100 kDa, and the deglycosylated Decorin core protein has a mass of approximately 40 kDa (5). Decorin regulates assembly of the extracellular collagen matrix and the bioactivity of the matrix associated growth factors FGF‑2, GDF‑8/Myostatin, TGF‑ beta, and WISP‑1 (4, 6 ‑ 9). It also binds and activates EGF R, ErbB4, and IGF‑I R (10 ‑ 12). In vivo, Decorin promotes myoblast differentiation, supports angiogenesis, and inhibits tumor progression (13 ‑ 16). Decorin is cleared from the extracellular space by LRP‑mediated endocytosis (17).
