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 Sodium Borate, 1.2 M Urea, 10 mM CaCl2, pH 8.0 
  • Recombinant Human Lysyl Oxidase Homolog 2/LOXL2 (rhLOXL2) (Catalog # 2639-AO)
  • Coupling Enzyme: Horseradish Peroxidase (HRP), 250 units/mL stock in 0.1 M Sodium Phosphate, pH 8.0
  • Substrate Component 1: Benzylamine, 100 mM stock in deionized water
  • Substrate Component 2: Amplex Ultra Red (AUR), 10 mM stock in DMSO
  • 96-well Black Plate
  • Plate Reader with Fluorescent Read Capability
  1. Prepare 50 mM Sodium Borate, 1.2 M Urea, pH 8.0 by dissolving Boric Acid and Urea in deionized water and adjusting the pH with Sodium Hydroxide.  Then, prepare the Assay Buffer by adding 1 M CaCl2 to a final concentration of 10 mM.
  2. Dilute rhLOXL2 to 10 ng/µL in Assay Buffer.
  3. Dilute Benzylamine to 4 mM in Assay Buffer.
  4. Combine equal volumes of 10 ng/µL rhLOXL2 and 4 mM Benzylamine. Also create a Substrate Blank by combining equal volumes of Assay Buffer and 4 mM Benzylamine.
  5. Incubate the reactions for 30 minutes at 37 °C.
  6. Prepare the Substrate Mixture, 2 units/mL HRP and 40 µM AUR, in Assay Buffer.
  7. Load 50 µL of the incubated reactions into the wells of a plate and add 50 µL of Substrate Mixture.
  8. Read at excitation and emission wavelengths of 544 nm and 590 nm (top read), respectively in endpoint mode. Note: A cutoff must be set manually at a wavelength of 570 nm.
  9. 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 Substrate Blank
     **Derived using a fluorescent standard prepared by incubating 20 µM AUR, 1 unit/mL HRP, 1 mM Benzylamine, and a curve of Hydrogen Peroxide in Assay Buffer. Use this oxidized AUR curve to determine the conversion factor.

Per Well:
  • rhLOXL2: 0.25 µg
  • Benzylamine: 1 mM
  • HRP: 1 unit/mL
  • AUR: 20 µM

Background: Lysyl Oxidase Homolog 2/LOXL2

Lysyl Oxidase Homolog 2 (lysyl oxidase-like protein 2, LOXL2) is a member of lysyl oxidase-like (LOXL) gene family which includes LOXL1 through LOXL4. These enzymes are secreted copper-binding amine oxidases that oxidize primary amine substrates to aldehydes (1). The N-terminal region of LOXL2 contains four scavenger receptor cysteine-rich (SRCR) domains, and the C-terminal region is a catalytic domain similar to other lysyl oxidases (1). The catalytic domain contains conserved residues required for copper binding and formation of a lysyl tyrosylquinone co-factor (2). Although some of the LOXL enzymes are known to cross-link collagen and elastin substrates, such a function has yet to be characterized for LOXL2. It has been shown that LOXL2 promotes cell migration and tumor cell invasiveness (3, 4). Elevated expression of LOXL2 is also associated with cancer progression in various tumors and carcinoma cell lines, which makes it a potential marker for prognosis of cancer (5). LOXL2 is expressed in many tissues, with elevated levels in reproductive tissues such as placenta, uterus, and prostate (6).
