Tech Info & Data



Many published reports indicate that ISG15 (G1P2) is commonly upregulated in response to Type I interferon stimulation. Though a wide range of cellular activites are influenced by ISG15 expression including Type I interferon signaling, translation, chromatin remodeling, cell motility, protein trafficking, and protein conjugation (ISGylation), the complete spectrum of ISG15-dependent biological sequelae remains to be fully elucidated. Further definition of new ISG15 target proteins and the role of free ISG15 will offer new insights into mechanistic and immunotherapeutic approaches to human diseases. This product detects conjugated and free ISG15.
