Packaging, Storage & Formulations

Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
  • 6 months from date of receipt, -20 to -70 °C as supplied.
  • 3 months, -20 to -70 °C under sterile conditions after opening.
Supplied as a 0.2 μm filtered solution in MES and NaCl.
>90%, by SDS-PAGE under reducing conditions and visualized by silver stain.
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

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).
