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.

Background: MMP-8

Matrix metalloproteinases (MMPs) are a family of zinc and calcium dependent endopeptidases with the combined ability to degrade all the components of the extracellular matrix. MMP-8 (neutrophil collagenase) is expressed in neutrophils, where it is stored in specific granules. MMP-8 release from the neutrophils is stimulated by various factors such as interleukins 1 and 8, TNF-alpha and GM-CSF. MMP-8 is capable of cleaving types I, II and III triple-helical collagen, gelatin peptides, fibronectin, proteoglycans, aggrecan, serpins, beta -casein and peptides such as angiotensin and substance P. In addition to its function in phagocytosis, MMP‑8 has a high capacity for infiltrating connective tissue, and is implicated in the breakdown of the extracellular matrix in diseases such as rheumatoid arthritis. Structurally, MMP-8 consists of several domains: a pro-domain that is cleaved upon activation, a catalytic domain containing the zinc-binding site, a short hinge region and a hemopexin-like domain. MMP-8 is heavily glycosylated.

FAQs

  1. Can the enzyme be stored after activation, or do I need to use it immediately after activation?

    • We recommend only activating the amount of enzyme needed for your assay, and recommend activating the enzyme immediately prior to use. Any unactivated enzyme should be stored in aliquots at either the stock concentration at which the enzyme was supplied, or the reconstitution concentration, according to the product datasheet.

  2. If I use this enzyme at a higher concentration, do I need to change the concentration of APMA to activate it?

    • We have only optimized activation conditions for one particular concentration of this MMP enzyme as part of our regular QC testing for enzymatic activity. Activating the enzyme at any different concentration would have to be optimized by the end user.

  3. Does this MMP enzyme need to be activated to work?

    • Yes, this enzyme requires activation prior to use.

  4. What is the activity of this enzyme in units/µg?

    • We supply this enzyme as a mass and calculate its activity relative to mass (pmol/min/µg). We have not calibrated this enzyme to an international standard unit, so we are unable to provide a conversion to units/µg.
