Description: Recombinant Human ISG15 Protein is produced by E. coli expression system and the target gene encoding Gly2-Gly157 is expressed with a 6His tag at the C-terminus. Form: Liquid in a 0.2 μM filtered solution of 50mM HEPES, 100mM NaCl, pH 8.0. Gene Symbol: ISG15 Alternative Names: G1P2; UCRP; Ubiquitin-like protein ISG15; Interferon-induced 15 kDa protein; Interferon-induced 17 kDa protein; IP17; Ubiquitin cross-reactive protein; hUCRPEntrez Gene (Human): 9636SwissProt (Human): P05161Purity : Greater than 95% as determined by reducing SDS-PAGE.Chemical Structure : GWDLTVKMLA GNEFQVSLSS SMSVSELKAQ ITQKIGVHAF QQRLAVHPSG VALQDRVPLA SQGLGPGSTV LLVVDKCDEP LNILVRNNKG RSSTYEVRLT QTVAHLKQQV SGLEGVQDDL FWLTFEGKPL EDQLPLGEYG LKPLSTVFMN LRLRGGLEHH HHHH Directions for Use : Always centrifuge tubes before opening. Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100 μg/ml. Dissolve the lyophilized protein in 1X PBS. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.Quality Control : Endotoxin: Less than 0.1 ng/μg (1 IEU/μg) as determined by LAL test.Storage/Stability : Store it at -20°C to -80°C for one year. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
