Recombinant Human Janus Kinase 2, His-tagged

• Cat.No.: JAK2-532H
• Product Overview: Recombinant human JAK2 was expressed by baculovirus inSf9 insect cellsusing an N-terminal His tag. MW=42.5kDa.

Specification

• Species: Human
• Source: Sf9 Cells
• Tag: His
• Description: JAK2 is a member of intracellular non-receptor tyrosine kinases that transduce cytokine-mediated signals via the JAK-STAT pathway. JAK2 has two near-identical phosphate-transferring domains. One domain exhibits the kinase activity while the other stabilizes the JAK conformational structure. JAK2 is the predominant JAK kinase activated in response to several growth factors and cytokines such as IL-3, GM-CSF and erythropoietin. JAK2 has been found to be constitutively associated with the prolactin receptor and is required for responses to gamma interferon.
• Purity: >90%.
