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: 50 mM Tris, pH 7.0
  • Recombinant Human Aminopeptidase N/CD13 (rhCD13) (Catalog # 3815-ZN)
  • Substrate: Ala-AMC (Bachem, Catalog # I-1410)
  • F16 Black Maxisorp Plate (Nunc, Catalog # 475515)
  • Fluorescent Plate Reader (Model: Spectramax Gemini EM by Molecular Devices) or equivalent

  1. Dilute rhCD13 to 0.2 µg/mL in Assay Buffer.
  2. Dilute Substrate to 200 µM in Assay Buffer.
  3. Load 50 µL of 0.2 µg/mL rhCD13 into a plate, and start the reaction by adding 50 µL of 200 µM Substrate. Include a Substrate Blank containing 50 µL of Assay Buffer and 50 µL of Substrate.
  4. Read at excitation and emission wavelengths of 380 nm and 460 nm (top read), respectively, in kinetic mode for 5 minutes.
  5. Calculate specific activity:

     Specific Activity (pmol/min/µg) =

 Adjusted Vmax* (RFU/min) x Conversion Factor** (pmol/RFU)
amount of enzyme (µg)

     *Adjusted for Substrate Blank

     **Derived using calibration standard 7-Amino-4-Methyl Coumarin (Sigma, Catalog # A9891).

Per Well:
  • rhCD13: 0.010 µg
  • Substrate: 100 µM

Background: Aminopeptidase N/CD13

The human ANPEP gene encodes aminopeptidase N (APN), which is also known as microsomal aminopeptiase, alanyl aminopeptidase, aminopeptidase M, CD13, or membrane protein p161 (1‑3). The deduced amino acid sequence of human APN consists of a short cytoplasmic tail (residues 2 to 8), a transmembrane region (residue 9 to 32), a Ser/Thr rich region and a zinc metalloprotease domain (residues 69 to 966). Widely expressed in many cells, tissues and species, APN cleaves the N-terminal amino acids from bioactive peptides, leading to their inactivation or degradation. The roles of APN in many fields, such as neuroscience, hematopoeitic cells, immune system, angiogenesis, cancer and viral infection, have been reviewed (3).
