Scientific Data Examples for Recombinant Human IFN-gamma GMP Protein, CF

	Recombinant Human IFN-gamma GMP Protein Bioactivity GMP-grade Recombinant Human IFN-gamma (Catalog # 285-GMP) demonstrates anti-viral activity in HeLa human cervical epithelial carcinoma cells infected with encephalomyocarditis (EMC) virus. The ED₅₀ for this effect is 0.15-0.75 ng/mL.
	Recombinant Human IFN-gamma GMP Protein SDS-PAGE 1 μg/lane of GMP-grade Recombinant Human IFN-gamma (Catalog # 285-GMP) was resolved with SDS-PAGE under reducing (R) conditions and visualized by silver staining, showing a single band at 17 kDa.
	Recombinant Human IFN-gamma GMP Protein Mass Spectrometry MALDI-TOF analysis of GMP-grade Recombinant Human IFN-gamma (Catalog # 285-GMP). The major peak corresponds to the calculated molecular mass, 16881 Da. The minor peak at 17099 Da is a matrix-associated artifact of the MALDI-TOF.

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: IFN-gamma

Interferon-gamma (IFN-gamma ), also known as type II or immune interferon, exerts a wide range of immunoregulatory activities and is considered to be the prototype proinflammatory cytokine (1, 2). Mature human IFN-gamma exists as a non-covalently linked homodimer of 20-25 kDa variably glycosylated subunits (3). It shares 90% amino acid (aa) sequence identity with rhesus IFN-gamma, 59%‑64% with bovine, canine, equine, feline, and porcine IFN‑ gamma, and 37%‑43% with cotton rat, mouse, and rat IFN-gamma. IFN-gamma dimers bind to IFN-gamma RI ( alpha subunits) which then interact with IFN-gamma RII ( beta subunits) to form the functional receptor complex of two alpha and two beta subunits. Inclusion of IFN-gamma RII increases the binding affinity for ligand and the efficiency of signal transduction (4, 5). IFN-gamma is produced by a variety of immune cells under inflammatory conditions, notably by T cells and NK cells (6). It plays a key role in host defense by promoting the development and activation of Th1 cells, chemoattraction and activation of monocytes and macrophages, up‑regulation of antigen presentation molecules, and immunoglobulin class switching in B cells. It also exhibits antiviral, antiproliferative, and apoptotic effects (6, 7). In addition, IFN-gamma functions as an anti-inflammatory mediator by promoting the development of regulatory T cells and inhibiting Th17 cell differentiation (8, 9). The pleiotropic effects of IFN-gamma contribute to the development of multiple aspects of atherosclerosis (7).
