Recombinant Human Fibrillin-1/FBN1 Fc Chimera Protein, CF Summary

Product Specifications

Purity

>95%, by SDS-PAGE under reducing conditions and visualized by silver stain.

Endotoxin Level

<0.10 EU per 1 μg of the protein by the LAL method.

Activity

Measured by its binding ability in a functional ELISA. When Recombinant Human MFAP4 (Catalog # 10230-MF) is immobilized at 0.5 μg/mL (100 μL/well), the concentration of Recombinant Human Fibrillin-1/FBN1 Fc Chimera (Catalog # 10224-FI) that produces 50% of the optimal binding response is 0.1-0.6 μg/mL.

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: Fibrillin-1/FBN1

Fibrillins are glycoproteins forming the backbone of microfibrils in elastic and non-elastic tissues. They interact with other components of the extracellular matrix (ECM) and play essential roles in tissue development, homeostasis and repair. Fibrillin-1 is a calcium-binding protein that assembles to form the structural component of the 10-12 nm microfibrils of the ECM. The human Fibrillin-1 has multiple domains, primarily consisting of epidermal growth factor (EGF)-like and other modules (1, 2). The calcium-binding modules in some of the EGF domains provide structural stability and the characteristic rod-like shape of the protein (3-8). Mature human Fibrillin-1 shares 97% amino acid (aa) sequence identity with mature mouse Fibrillin-1. Human Fibrillin-1 is synthesized as an approximately 350-kDa precursor molecule, which is then proteolytically processed by furin into its biologically active form (9-10). Fibrillin microfibers are further engaged in a number of cell matrix interactions such as with integrins, bone morphogenetic proteins (BMPs) and the large latent complex of transforming growth factor-beta (11). Fibrillin-1 mutations are associated with a range of heritable connective disorders, including Marfan syndrome and acromelic dysplasias (11-12).
