Tested in Flow Cytometry, IF, ICC, WB applications. This antibody reacts with Human. The brand Picoband indicates this is a premium antibody that guarantees superior quality, high affinity, and strong signals with minimal background in Western blot applications. Only our best-performing antibodies are designated as Picoband, ensuring unmatched performance.\u003cp\u003eEIF2AK2 (Eukaryotic Translation Initiation Factor 2-Alpha Kinase 2), also called PKR, is an enzyme that in humans is encoded by the EIF2AK2 gene. Activation of EIF2AK2 allows the kinase to phosphorylate its natural substrate, the alpha subunit of eukaryotic protein synthesis initiation factor-2, leading to the inhibition of protein synthesis. By FISH analysis, Squire et al. (1993) assigned the EIF2AK2 gene to the boundary between chromosome 2p22-p21. Ben-Asouli et al. (2002) showed that human gamma-interferon mRNA uses local activation of PKR in the cell to control its own translation yield. IFNG mRNA was found to activate PKR through a pseudoknot in its 5-prime untranslated region. Taylor et al. (1999) studied the mechanism underlying the resistance of hepatitis C virus (HCV) to interferon. They demonstrated that the HCV envelope protein E2 contains a sequence identical with phosphorylation sites of the interferon-inducible protein kinase PKR and the translation initiation factor EIF2-alpha, a target of PKR. E2 inhibited the kinase activity of PKR and blocked its inhibitory effect on protein synthesis and cell growth.\u003c\/p\u003e\u003ch3\u003eProduct information\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eSupplier\u003c\/th\u003e\n\u003ctd\u003eBoster Bio\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eABMIUM evidence status\u003c\/th\u003e\n\u003ctd\u003eABMIUM Verified™ collaborator-tested data\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCatalogue reference\u003c\/th\u003e\n\u003ctd\u003ePB9803\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eProduct category\u003c\/th\u003e\n\u003ctd\u003ePrimary Antibodies\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eReactive species\u003c\/th\u003e\n\u003ctd\u003eHuman\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTested applications\u003c\/th\u003e\n\u003ctd\u003eELISA, Flow Cytometry, IF\/ICC, IHC, IHC-P, WB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eAvailable conjugations\u003c\/th\u003e\n\u003ctd\u003eUnconjugated, Biotin, Cy3, Fluoro488, Fluoro550, Fluoro594, FITC, HRP, APC, PE, Fluoro647\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eGene name\u003c\/th\u003e\n\u003ctd\u003eEIF2AK2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eProtein name\u003c\/th\u003e\n\u003ctd\u003eInterferon-induced, double-stranded RNA-activated protein kinase\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSpecificity\u003c\/th\u003e\n\u003ctd\u003eNo cross reactivity with other proteins.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eImmunogen\u003c\/th\u003e\n\u003ctd\u003eA synthetic peptide corresponding to a sequence at the C-terminus of human PKR, different from the related mouse sequence by fifteen amino acids, and from the related rat sequence by thirteen amino acids.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHost\u003c\/th\u003e\n\u003ctd\u003eRabbit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eClonality\u003c\/th\u003e\n\u003ctd\u003ePolyclonal\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eIsotype\u003c\/th\u003e\n\u003ctd\u003eRabbit IgG\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePurification\u003c\/th\u003e\n\u003ctd\u003eImmunogen affinity purified.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eStorage\u003c\/th\u003e\n\u003ctd\u003eStore at -20℃ for one year from date of receipt.
