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.

8146-GD

Background: GDF-15

Growth Differentiation Factor 15 (GDF-15), also called Macrophage Inhibitory Cytokine 1 (MIC-1), Placental Transforming Growth Factor beta, Prostate-derived Factor, and Placental Bone Morphogenetic Protein, is a divergent member of the Transforming Growth Factor beta (TGF-beta ) superfamily (1, 2). Human GDF-15 shares 66% and 68% amino acid sequence identity with the rat and mouse proteins, respectively (3). GDF-15 is highly expressed in placenta and brain, and it is expressed at lower levels in kidney, pancreas, prostate, and colon. Similar to other TGF-beta family proteins, GDF-15 is synthesized as a large precursor protein that is cleaved at a dibasic cleavage site (RxxR) to release the mature protein. The C-terminal domain of GDF-15 contains seven characteristic conserved cysteine residues necessary for the formation of the cysteine knot and the single inter-chain disulfide bond (4, 5). Biologically active GDF-15 is a disulfide-linked homodimer of the mature protein. GDF‑15 has been shown to have various functions, including inhibition of Tumor Necrosis Factor alpha (TNF-alpha ) production from lipopolysaccharide-stimulated macrophages and the induction of cartilage formation (1, 6). GDF-15 also promotes neuronal survival, and hypothalamic expression of GDF-15 causes appetite suppression via modulation of neuropeptide Y and pro-opiomelanocortin levels (7-10). GDF-15 is cardioprotective via inhibition of platelet activation, limiting atherosclerosis, promoting recovery following myocardial infarction, and regulating angiogenesis (11-15). Exposure of cardiomyocytes to GDF-15 results in Smad2 and Smad3 phosphorylation (16).
