pJAK2(1001-1013)
Based on 1 Customer Validation
pJAK2(1001-1013) is a cell-penetrating peptide that corresponds to the activation loop of JAK2 tyrosine kinase and functions as a SOCS1/3antagonist. pJAK2 (1001-1013) blocks SOCS1-mediated negative regulation of immune function, and enhances the biological activity of cytokines such as IFNγ and IL6. pJAK2(1001-1013) inhibits the replication of a broad range of viruses and exerts dose-dependent protective efficacy against lethal viral infections. pJAK2(1001-1013) can be used for the study of immune regulation and infection.

-
Animal Model:C57BL/6 mice were intranasally challenged with a lethal dose of vaccinia virus or infected with encephalomyocarditis virus (EMCV) to establish a viral infection model[1]
-
Dosage:10 μg, 50 μg, 200 μg
-
Administration:i.p., on days -2, -1, and 0 relative to virus challenge, once per day or every other day starting from day 2 post-virus infection
-
Result:Achieved dose-dependent protective efficacy.
-
Animal Model:C57BL/6 mice (used for Ag-specific immune response evaluation) were intraperitoneally injected with 50 μg bovine serum albumin (BSA) to establish an Ag-specific immune model[2]
-
Dosage:200 μg/mouse
-
Administration:i.p., on day -2, -1, and 0 relative to BSA immunization
-
Result:Enhanced Ag-specific splenocyte proliferation 4 weeks post-BSA injection.
-
Animal Model:Mouse-adapted influenza A/PR8 virus (10×LD50 pfu in 10 μL PBS) was intranasally administered to 6-8-week-old female C57BL/6 mice, with 5 μL delivered into each nostril of lightly anesthetized mice[3]
-
Dosage:200 μg/mouse
-
Administration:i.p., once daily for 1 week
