Recombinant Mouse CTRP9/C1qTNF9 His-tag Protein, CF Summary

Purity
>95%, by SDS-PAGE visualized with Silver Staining and quantitative densitometry by Coomassie® Blue Staining.
Endotoxin Level
<0.10 EU per 1 μg of the protein by the LAL method.
Activity
Measured by its binding ability in a functional ELISA. When Recombinant Mouse CTRP9/C1qTNF9 is immobilized at 0.5 µg/mL (100 µL/well), the concentration of Biotinylated Recombinant Human CL-K1/COLEC11 that produces 50% of the optimal binding response is 15-90 ng/mL.

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: CTRP9/C1qTNF9

C1qTNF9, also known as CTRP9, is an approximately 40 kDa member of the C1q and TNF-related protein family (1). Like all members of this protein family, C1qTNF9 consists of a short variable region, a collagenous domain that can be hydroxylated, and a C1q-like globular domain (1). Mouse C1qTNF9 shares 86% and 98% amino acid sequence identity with the human and rat orthologs, respectively. Both the mouse and human C1qTNF9 proteins are expressed mostly in adipose tissue, but the mouse protein has also been detected in the heart, lung, muscle, kidney, testis, lymph node, smooth muscle, prostate, thymus, and uterus (1, 2). C1qTNF9 has been shown to be secreted as trimers and higher order multimers and also to form hetero-oligomers with Adiponectin (1, 2). Mouse C1qTNF9 can stimulate the phosphorylation of AMPK, Akt, and eNOS (1, 3, 4). Also in mice, C1qTNF9 may have an important role in cardiac and metabolic health. Its expression has a cardioprotective effect following acute myocardial infarction that may be dependent on AMPK activation (4-6). Additionally, transgenic mice overexpressing C1qTNF9 are resistant to high fat diet‑induced obesity (7). This metabolic role may be conserved, since C1qTNF9 serum levels have been shown to inversely correlate with metabolic syndrome in humans (8).
