Animal-Free IL-9 Protein, Mouse (His)

Cat. No.: HY-P700218AF
COA Handling Instructions

IL-9 is secreted by T helper 2 lymphocytes, mast cells, and NKT cells and plays an important role in antiparasitic immune responses, affecting intestinal permeability, adaptive immunity, and T cell subset differentiation. It promotes TH17 cell and mast cell proliferation through IL9R and IL2RG receptor activation, triggering JAK1 and JAK3 kinases and subsequent STAT-mediated transcription. Animal-Free IL-9 Protein, Mouse (His) is the recombinant mouse-derived animal-FreeIL-9 protein, expressed by E. coli , with N-His labeled tag. The total length of Animal-Free IL-9 Protein, Mouse (His) is 126 a.a., with molecular weight of ~14.97 kDa.

Animal-free recombinant proteins offer high consistency and stability, whithout using or contacting of any animal-derived materials and reagents.

Background

IL-9, a multifunctional cytokine primarily secreted by T-helper 2 lymphocytes and also by mast cells or NKT cells, assumes crucial roles in the immune response against parasites. Beyond its anti-parasitic function, IL-9 influences intestinal epithelial permeability and adaptive immunity. It plays a pivotal role in inducing the differentiation of specific T-cell subsets, such as IL-17-producing helper T-cells (TH17), and promotes the proliferation and differentiation of mast cells. Mechanistically, IL-9 exerts its diverse biological effects through a receptor comprised of the IL9R subunit and the signal transducing subunit IL2RG. Stimulation of this receptor leads to rapid activation of JAK1 and JAK3 kinase activities, initiating STAT1, STAT3, and STAT5-mediated transcriptional programs. The induction of differentiation genes appears to be mediated by STAT1 alone, while the protection of cells from apoptosis depends on the concerted actions of STAT3 and STAT5. IL-9 interacts directly with IL9R and IL2RG, orchestrating a sophisticated network of interactions to modulate immune responses and cellular processes.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.

  • Specific Activity Calculator

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

The specific activity calculator equation

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
