Interferon Stimulating Gene 15 (ISG15) is a member of the ubiquitin-like protein family and functions in various biological pathways from pregnancy to innate immune responses. Expression of ISG15 is stimulated by cellular exposure to type 1 interferons alpha and beta, in addition to infection with viruses such as influenza B. After exposure to type I interferons, both lymphocytes and monocytes, in addition to some fibroblasts and epithelial cells, release ISG15 into culture medium. ISG15 has been shown to function as a cytokine, stimulating interferon gamma secretion by monocytes and macrophages, proliferation of natural killer cells, and chemotactic responses in neutrophils. ISG15 has also been shown to function intracellularly, being covalently conjugated to other proteins by E1 (Ube1L), E2 (UbcH8) and E3 ligases via a multi-step process analogous to ubiquitination. ISG15 is removed from proteins by the ubiquitin processing protease Ubp43. ISG15-protein conjugation (ISGylation) is induced by type 1 interferons, and target proteins include the serine protease inhibitor Serpin 2A, PLC gamma1, ERK1/2, Jak1 and Stat1. Unlike ubiquitination, ISGylation does not target proteins for degradation, rather ISGylation increases Jak1 and Stat1 activity, enhancing the cellular response to interferons. Applications: Suitable for use in ELISA, Western Blot and Immunoprecipitation. Other applications not tested. Recommended Dilution: Western Blot: 1:1000 Immunoprecipitation: 1:25 Optimal dilutions to be determined by the researcher. Storage and Stability: May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.

Calc Crossreactivity :
