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.

Assay Procedure

Materials
  • Assay Buffer: 25 mM HEPES, 0.01% (w/v) Brij-35, pH 7.0
  • Recombinant Human Aggrecan Aggrecan G1-IGD-G2 Domains (rhAggrecan) (Catalog # 1220-PG)
  • Recombinant Mouse ADAMTS1 Recombinant Mouse ADAMTS1 (rmADAMTS1) (Catalog # 5867-AD)
  • SDS-PAGE and/or Western blot
  1. Dilute rhAggrecan to 200 µg/mL in Assay Buffer.
  2. Dilute rmADAMTS1 to 20 µg/mL in Assay Buffer.
  3. Combine 25 µL of 200 µg/mL rhAggrecan with 25 µL of 20 µg/mL rmADAMTS1 in a reaction tube.
  4. Incubate the reaction mixture for 24 hours at 37 °C.
  5. For Controls: Combine 25 µL of rhAggrecan solution and 25 µL of Assay Buffer into two tubes. Incubate one tube at 37 °C and the other at -20 °C for 24 hours.
  6. Stop the reaction by adding reduced SDS-PAGE sample buffer.
  7. Analyze the cleavage by SDS PAGE followed by protein staining and/or Western blot.
Per Reaction:
  • rmADAMTS1: 10 µg/mL (0.5 µg)
  • rhAggrecan: 100 µg/mL (5 µg)

Background: ADAMTS1

ADAMTS1 (a disintegrin and metalloproteinase with thrombospondin motifs 1), also known as METH1, is the founding member of the family of secreted zinc proteases with a multidomain structure (1-3). The protein precursor consists of a signal peptide and the following domains: pro, catalytic, disintegrinlike, TS type 1 motif, cysteine rich, spacer and a variable number of thrombospondin type 1 motifs. Based on their substrate specificity, ADAMTS1 and associated family members may be key enzymes in the degradation of cartilage leading to inflammation and arthritis (4). It is an active protease cleaving alpha 2macroglobulin (5), aggrecan (6), and versican (7). Compared to ADAMTS4 (aggrecanase 1) and ADAMTS5 (aggrecanase 2), the aggrecanase activity of ADAMTS1 is lower. However, its activity can be enhanced by the binding of a cofactor such as fibulin1 (8). ADAMTS1 is essential for normal growth and the structure and function of the kidneys, adrenal glands and female reproductive organs (9). It also plays an important role in atherosclerosis (10). It has been shown to inhibit endothelial cell proliferation by direct binding and sequestration of VEGF165 and to inhibit fibroblast migration at high concentrations by binding to FGF 2 (11, 12). The purified rmADAMTS1 starts at the N terminus of the catalytic domain and ends in the Cys-rich domain.
