Formulation, Preparation and Storage

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: Fibroblast Activation Protein alpha/FAP

FAP (also known as seprase) is a 95 kDa Type II transmembrane serine protease that forms a homodimer and is structurally related to the dipeptidyl peptidase IV (DPPIV/CD26) family with a short cytoplasmic tail, a single transmembrane domain, and an extracellular domain that contains the active site (1-3). Within the extracellular domain, cynomolgous FAP shares 99.6% and 89.8% amino acid (aa) sequence identity with human and mouse FAP, respectively. It exhibits dipeptidyl peptidase activity with substrate specificity similar to DPPIV, which is specific for N-terminal Xaa-Pro sequences (4, 5). FAP is also an endopeptidase that can degrade Gelatin, Collagens I and IV, Fibronectin, and Laminin (1, 4, 5) as well as several peptide hormones (e.g. Neuropeptide Y, Brain Natriuretic Peptide, Substance P, Peptide YY, and Incretins) (6). FAP is also known to interact with several surface molecules to play roles in cell signaling, cell invasion and migration (3). Although not detectible in normal tissues, FAP is elevated in activated stromal fibroblasts, tumor-associated macrophages, activated hepatic stellate cells and myofibroblasts during pathological conditions that include tissue remodeling such as most types of cancer, wound healing, arthritis, atherosclerosis, and fibrosis (1, 3, 4, 7-9). Targeting FAP with vaccines, antibodies, or pharmacologics impairs tumor progression in several cancer models making it a promising immunotherapy target (9-12).
