IL-35 Protein, Human (HEK293, His, hFc-Flag)

Cat. No.: HY-P73882
COA Handling Instructions

IL-35 protein plays a key role in immune regulation, forming IL-12 cytokine with IL12B or IL-35 cytokine with EBI3/IL27B. IL-12 modulates T cell and natural killer cell responses and induces interferon gamma production. IL-35 Protein, Human (HEK293, His, hFc-Flag) is a recombinant protein dimer complex containing human-derived IL-35 protein, expressed by HEK293 , with C-hFc, C-Flag, C-8*His labeled tag.

Description

IL-35 protein plays a key role in immune regulation, forming IL-12 cytokine with IL12B or IL-35 cytokine with EBI3/IL27B. IL-12 modulates T cell and natural killer cell responses and induces interferon gamma production. IL-35 Protein, Human (HEK293, His, hFc-Flag) is a recombinant protein dimer complex containing human-derived IL-35 protein, expressed by HEK293 , with C-hFc, C-Flag, C-8*His labeled tag.

Background

IL-35 Protein plays a pivotal role in immune regulation, exhibiting versatility in its functions. It heterodimerizes with IL12B to form the IL-12 cytokine or with EBI3/IL27B to create the IL-35 cytokine. IL-12, primarily produced by professional antigen-presenting cells such as B-cells, dendritic cells, macrophages, and granulocytes, serves as a crucial link between innate resistance and adaptive immunity, regulating T-cell and natural killer-cell responses while inducing interferon-gamma production and favoring the differentiation of T-helper 1 cells. Mechanistically, IL-12 exerts its effects through a receptor composed of IL12R1 and IL12R2 subunits, leading to tyrosine phosphorylation of cellular substrates and subsequent regulation of cytokine/growth factor responsive genes by recruited phosphorylated STAT4. In the context of IL-35, IL-35 contributes significantly to maintaining immune homeostasis in the liver microenvironment and functions as an immune-suppressive cytokine. Notably, IL-35 mediates its effects through unconventional receptors composed of IL12RB2 and gp130/IL6ST heterodimers or homodimers, requiring the transcription factors STAT1 and STAT4 for signaling. Additionally, IL-35 interacts with NBR1, promoting IL-12 secretion. The IL-35 heterodimer with EBI3/IL27B, known as interleukin IL-35, is not disulfide-linked, distinguishing it from the disulfide-linked IL-12 heterodimer with IL12B.

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.

  • 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)
× = ×

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
