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
  • Activation Buffer: 25 mM MES, 5 mM DTT, pH 6.0
  • Assay Buffer: 25 mM MES, 50 mM NaCl, 5 mM DTT, pH 6.0
  • Recombinant Human Cathepsin C/DPPI (rhCathepsin C) (Catalog # 1071-CY)
  • Recombinant Human Cathepsin L (rhCathepsin L) (Catalog # 952-CY)
  • Substrate: Gly-Arg-AMC (Bachem, Catalog # I-1215), 10 mM stock in DMSO
  • F16 Black Maxisorp Plate (Nunc, Catalog # 475515)
  • Fluorescent Plate Reader (Model: SpectraMax Gemini EM by Molecular Devices) or equivalent

  1. Dilute rhCathepsin C to 200 µg/mL in Activation Buffer.
  2. Add rhCathepsin L and Activation Buffer to rhCathepsin C for final concentrations of 20 µg/mL rhCathepsin L and 100 µg/mL rhCathepsin C.
  3. Incubate at room temperature for 1 hour.
  4. Dilute activated rhCathepsin C to 0.5 ng/µL in Assay Buffer.
  5. Dilute Substrate to 20 µM in Assay Buffer.
  6. Load 50 µL of the 0.5 ng/µL rhCathepsin C into a black well plate, and start the reaction by adding 50 µL of 20 µM Substrate. Include a Substrate Blank containing 50 µL Assay Buffer and 50 µL of 20 µM Substrate without any rhCathepsin C.
  7. Read at excitation and emission wavelengths of 380 nm and 460 nm (top read), respectively, in kinetic mode for 5 minutes.
  8. 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 (AMC) (Sigma, Catalog # A-9891).

  • rhCathepsin C: 0.025 µg
  • Substrate: 10 µM
Reconstitution Calculator

Background: Cathepsin C/DPPI

Cathepsin C, also known as dipeptidyl-peptidase I (DPPI), is a cysteine protease of the papain family (1). Cathepsin C sequentially removes dipeptides from the free N-termini of proteins and peptides. It has broad specificity except that it does not cleave a basic amino acid (Arg or Lys) in the N-terminal position or Pro on either side of the scissle bond. It requires halide ions for activity. The pro form contains a pro peptide and a catalytic region, which can be further processed into heavy/ alpha and light/ beta chains that are linked by a disulfide bond. It is broadly distributed. Cathepsin C plays a role in the lysosomal degradation. It also functions as a key enzyme in the activation of granule serine proteases in cytotoxic T lymphocytes and natural killer cells (granzymes A and B), mast cells (tryptase and chymase), and neutrophils (Cathepsin G and elastase) by removing their N-terminal activation dipeptides (2). Loss of function mutations in the Cathepsin C gene result in periodontal disease and palmoplantar keratosis (3).

Recombinant Human Cathepsin C/DPPI Protein, CF
By Anonymous on 06/24/2016
Application: Binding assay/Protein-protein interaction
Reason for Rating: While Cathepsin did activate ms Neutrophil elastase Cat No. 4517-SE-010 the amount of total protein activated was less. The Activity assay of NE after cathepsin activation was not at 100% compared to a control hu NE sample.

I ran the activity assay at greater than 1ng/mL.
