Active Recombinant Human IL15, HIgG1 Fc-tagged

• Cat.No.: IL15-006H
• Product Overview: The extracellular domain of human IL-15(NP_751914.1)(Asn49-Ser162) including mutations at Q149D and Q156D is fused to the N-terminus of the Fc region of human IgG1 was expressed in CHO cell.

Specification

• Species: Human
• Source: CHO
• Tag: Fc
• Protein Length: 49-162 a.a.
• Description: The protein encoded by this gene is a cytokine that regulates T and natural killer cell activation and proliferation. This cytokine and interleukine 2 share many biological activities. They are found to bind common hematopoietin receptor subunits, and may compete for the same receptor, and thus negatively regulate each other"s activity. The number of CD8+ memory cells is shown to be controlled by a balance between this cytokine and IL2. This cytokine induces the activation of JAK kinases, as well as the phosphorylation and activation of transcription activators STAT3, STAT5, and STAT6. Studies of the mouse counterpart suggested that this cytokine may increase the expression of apoptosis inhibitor BCL2L1/BCL-x(L), possibly through the transcription activation activity of STAT6, and thus prevent apoptosis. Alternatively spliced transcript variants of this gene have been reported
• Form: Lyophilized from 0.2μm-filtered solution in PBS.
• Bio-activity: This mutant IL-15/Fc fusion protein specifically binds to the IL-15R, competitively inhibits IL-15-triggered cell proliferation, promotes transplant tolerance, does not activate the STATsignaling pathway, and exerts a prolonged circulating half-life cause
• Molecular Mass: 41 KDa (monomer)
• AA Sequence: Asn49-Ser162
• Purity: >98%, by SDS-PAGE under reducing conditions.
