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 Supplied as a 0.2 μm filtered solution in MES and NaCl.
Shipping The product is shipped with polar packs. Upon receipt, store it immediately at the temperature recommended below.
Stability & Storage: Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
  • 6 months from date of receipt, -20 to -70 °C as supplied.

Assay Procedure

  • Assay Buffer: 25 mM Tris, 2.5 µM ZnCl2, 0.005% (w/v) Brij-35, pH 9.0
  • Recombinant Human ADAM-9 (rhADAM9) (Catalog # 939-AD)
  • Fluorogenic Peptide Substrate III: MCA-Pro-Leu-Ala-Gln-Ala-Val-DPA-Arg-Ser-Ser-Ser-Arg-NH2 (Catalog # ES003)
  • F16 Black Maxisorp Plate (Nunc, Catalog # 475515)
  • Fluorescent Plate Reader (Model: SpectraMax Gemini EM by Molecular Devices) or equivalent
  1. Dilute rhADAM9 to 40 µg/mL in Assay Buffer.
  2. Dilute substrate to 20 µM in Assay Buffer.
  3. Combine equal volumes of 40 µg/mL rhADAM9 and 20 µM substrate. Include a control containing Assay Buffer and 20 µM substrate without any rhADAM9.
  4. Incubate reactions at 37 °C for 30 minutes.
  5. Load 100 μL of reactions and control per well in a black plate.
  6. Read with excitation and emission wavelengths of 320 nm and 405 nm (top read), respectively, in endpoint mode.
  7. Calculate specific activity:

     Specific Activity (pmol/min/µg) =

Adjusted Fluorescence* (RFU) x Conversion Factor** (pmol/RFU)
Incubation time (min) x amount of enzyme (µg)

     *Adjusted for Control
     **Derived using calibration standard MCA-Pro-Leu-OH (Bachem, Catalog # M-1975).

Per Well:
  • rhADAM9: 2.0 µg
  • Substrate: 10 µM

Background: ADAM9

ADAM9, also known as MDC9 or meltrin gamma, is a member of the ADAM family that contains a disintegrin and metalloprotease‑like domain (1). Like other membrane-anchored ADAMs, ADAM9 consists of a pro domain with a cysteine switch and furin cleavage sequence, a catalytic domain with the zinc‑binding site and Met-turn expected for reprolysins, a disintegrin-like domain, a cysteine-rich domain, an EGF-like domain, a transmembrane domain, and the cytoplasmic domain. ADAM9 is able to cleave peptides corresponding to cleavage sites of tumor necrosis factor-alpha (TNF-alpha ), the p75 TNF receptor, the beta -amyloid protein precursor, and the c‑kit ligand-1, implying that it may participate in shedding of these membrane proteins (2). In fact, ADAM9 has been shown to shed membrane‑anchored heparin-binding EGF-like growth factor (3). In addition, it also cleaves oxidized insulin beta -chain and fibronectin (2,4). Besides its catalytic activity, ADAM9 functions as an adhesion molecule through binding of its disintegrin domain to integrins such as alpha v beta 5 and alpha 6 beta 1 (5, 6). The cytoplasmic domain of ADAM9 interacts with Src homology 3
(SH3)‑containing proteins and protein kinase C, and may mediate different signaling pathways (3, 7). ADAM9 is widely expressed in tissues (8).
