IL-31 is a multifunctional cytokine that activates STAT3 through IL-31 heterodimeric receptors (IL31RA and OSMR) and may activate STAT1 and STAT5. IL-31 is known for its involvement in skin immunity, where it regulates immune responses. IL-31 Protein, Human (HEK293) is the recombinant human-derived IL-31 protein, expressed by HEK293, with tag free.

Description

IL-31 is a multifunctional cytokine that activates STAT3 through IL-31 heterodimeric receptors (IL31RA and OSMR) and may activate STAT1 and STAT5. IL-31 is known for its involvement in skin immunity, where it regulates immune responses. IL-31 Protein, Human (HEK293) is the recombinant human-derived IL-31 protein, expressed by HEK293, with tag free.
Background

IL-31, a cytokine with diverse functions, acts by activating STAT3, and potentially STAT1 and STAT5, utilizing the IL-31 heterodimeric receptor formed by IL31RA and OSMR. This activation mechanism has been implicated in skin immunity, highlighting its role in modulating immune responses. Additionally, IL-31 exhibits the capacity to enhance myeloid progenitor cell survival in vitro, emphasizing its involvement in cellular processes beyond immune regulation. Furthermore, IL-31 induces the expression of key genes, such as RETNLA and serum amyloid A protein, in macrophages, suggesting a broader impact on inflammatory and immune-related pathways.

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.

  • Reconstitution Calculator

  • Dilution Calculator

  • 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)
× = ×
C1   V1   C2   V2

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
