Recombinant Human Fibulin 3 Protein, CF Summary
Gln18-Phe493 with N-terminal HA tag
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.
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: Fibulin 3
Human Fibulin-3, also called EGF-containing fibulin-like extracellular matrix protein 1 (EFEMP-1), is an approximately 57 kDa member of the fibulin family of proteins (1). It was originally identified in fibroblasts from a Werner syndrome patient with premature aging (2). Along with Fibulin-4 and -5, Fibulin-3 is referred to as a class II, or short fibulin (3). Fibulin-3 contains five calcium-binding EGF-like motifs and a fibulin-type C terminus (1). Human Fibulin-3 shares 95% and 93% amino acid sequence identity with mouse and rat Fibulin-3, respectively. It has been shown to be susceptible to MMP-mediated proteolysis (4). Fibulin-3 appears to be involved in the proper function of elastic tissues. Knockout mice are viable, but display disrupted elastic fibers in fascia connective tissue of the body wall (5, 6). In humans, Fibulin-3 mutations have been associated with Doyne honeycomb retinal dystrophy (7). Its expression is up-regulated in late, metastatic stages of carcinomas, suggesting that it may play a role in cancer (8, 9). Fibulin-3 promotes the growth of gliomas and may have a pro-angiogenic role in this cancer type (10, 11). In contrast, Fibulin-3 has been shown to negatively modulate the invasiveness of lung cancer cells and inhibit self-renewal of lung cancer stem cells (12-14).
