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, 0.1% Brij-35 (w/v), pH 7.5
  • Recombinant Human BMP‑1/PCP (rhBMP-1) (Catalog # 1927-ZN)
  • Fluorogenic Peptide Substrate: MCA-Tyr-Val-Ala-Asp-Ala-Pro-Lys(DNP)-OH (Catalog # ES007)
  • F16 Black Maxisorp Plate (Nunc, Catalog # 475515)
  • Fluorescent Plate Reader (Model: SpectraMax Gemini EM by Molecular Devices) or equivalent
  1. Dilute rhBMP-1 to 20 ng/µL in Assay Buffer.
  2. Dilute substrate to 20 µM in Assay Buffer.
  3. Load into a black well plate 50 µL of 20 ng/µL rhBMP-1 and start the reaction by adding 50 µL of 20 µM Substrate. Include a Substrate Blank containing Assay Buffer in place of rhBMP-1.
  4. Read at excitation and emission wavelengths of 320 nm and 405 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 MCA-Pro-Leu-OH (Bachem, Catalog # M-1975).

Per Well:
  • rhBMP-1: 1 µg
  • Substrate: 10 µM

Background: BMP-1/PCP

Bone morphogenetic protein 1 (BMP‑1), also known as procollagen C‑proteinase (PCP), is a zinc protease of the astacin family (1, 2). BMP‑1/PCP plays a key role in formation of extracellular matrix (ECM) by converting precursor proteins into their mature and functional forms. The precursor proteins identified as substrates for BMP‑1/PCP include collagens, biglycan, laminin 5, dentin matrix protein‑1, and lysyl oxidase (3). There are six alternatively spliced forms known to be derived from the BMP‑1 gene, and isoform 1 consisting of residues 1 to 730 was expressed. The secreted and purified protein does not contain the signal peptide (amino acid residues 1‑22) and pro domain (residues 23‑120), but contain protease (residues 121‑321), CUB I (residues 322‑434), CUB II (residues 435‑546), EGF‑like (residues 547‑588) and CUB III (residues 591‑703) domains. The pro domain is apparently cleaved by a furin‑like proprotein convertase (4). The purified BMP‑1/PCP is an active protease and its peptidase activity can be determined as described above. The purified BMP‑1/PCP is predicted to possess procollagen C‑proteinase activity because it contains the minimal domain structure required (5).
