Working concentrations for specific applications should be determined by the investigators. The appropriate concentration may be affected by secondary antibody affinity, antigen concentration, the sensitivity of the method of detection, temperature, the length of the incubations, and other factors. The suitability of this antibody for applications other than those listed below has not been determined. The following concentration ranges are recommended starting points for this product. ELISA detection: 0.02-0.1 ug/ml Western blot: 1 ug/ml Other applications: user-optimized

The lyophilized product remains stable up to 1 year at -20 C from date of receipt. Upon reconstitution, it can be stored for 2-3 weeks at 2-8 C or for up to 12 months at -20 C or below. Avoid repeated freezing and thawing cycles.

Interferon-gamma (IFN-gamma) is a pro-inflammatory cytokine that is central in host resistance to infection. It is mainly produced by natural killer cells and CD4+ and CD8+ T cells. Its receptors are found on nearly all cells, where it activates diverse responses that enable potential host cells to prevent invasive infection by bacteria, parasites, and viruses. Takayanagi et al. (2000) demonstrated that IFN-gamma strongly suppresses osteoclastogenesis by interfering with the RANKL (602642)-RANK (603499) signaling pathway. Tsubota et al. (1999) reported that this upregulation in Sjogren syndrome patients may be controlled by interferon-gamma through the activation of transcription factor NF-KB.
