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: IFN-beta

Interferon beta (IFN-beta ), also known as fibroblast IFN, is a secreted, approximately 22 kDa member of the type I interferon family of molecules (1). Mature human IFN-beta shares 47% and 46% amino acid sequence identity with the mouse and rat proteins, respectively. Fibroblasts are the major producers of IFN-beta, but it can also be produced by dendritic cells, macrophages, and endothelial cells in response to pathogen exposure (2). It is transcriptionally regulated by TRAF3, IRF3, IRF7, and NF-kappa B (3, 4). Following secretion, IFN-beta signals through the heterodimeric IFN-alpha / beta Receptor and activates the JAK/STAT signaling pathway (5-8). IFN-beta -deficient mice show increased susceptibility to experimental autoimmune encephalomyelitis (EAE), a disease model of human multiple sclerosis (MS) (9). Furthermore, IFN-beta has been shown to suppress the Th17 cell response in both MS and EAE and has commonly been used as a treatment for MS (10-14).

FAQs

  1. Is there a mass to unit conversion for Recombinant Human IFN-beta Protein (Catalog # 8499-IF & 8499-IF/CF)?

    • We have developed a mass to unit conversion factor for Recombinant Human IFN-beta Protein (Catalog # 8499-IF & 8499-IF/CF) using a NIBSC reference standard (00/572). In this testing, we found a relative conversion of 1 ug of cytokine = 2.8 x 105 Units. This information can be found in our Unit Conversion Table: https://www.rndsystems.com/resources/technical-information/unit-conversion-table

      Please note that this is a relative conversion factor and concentration optimization may be necessary for individual applications.

Application: Gene expression
Reason for Rating: Treatment of HeLa cells with this recontaminated interferon beta was able to upregulate OAS1, a well-known interferon-stimulated gene. Fold change was not as strong as expected, but it worked.
