IL-37 Protein, Human (166a.a)

Cat. No.: HY-P73879
COA Handling Instructions

IL-37 Protein, a crucial immune regulatory cytokine, suppresses innate inflammatory and immune responses, mitigating excessive inflammation. It signals intracellularly via nuclear translocation with SMAD3 and extracellularly by binding to its receptor, composed of IL18R1 and IL18RAP. IL-37 inhibits pro-inflammatory cytokines, sparing anti-inflammatory ones, and hinders dendritic cell activation. It interacts with SMAD3, binds IL18R1 (with lower affinity than IL18), and forms a complex with TMED10 for secretion. IL-37 Protein, Human (166a.a) is the recombinant human-derived IL-37 protein, expressed by E. coli , with tag free. The total length of IL-37 Protein, Human (166a.a) is 166 a.a., with molecular weight of ~18.7 kDa.

Background

IL-37 Protein, an immune regulatory cytokine, plays a pivotal role as a suppressor of innate inflammatory and immune responses, mitigating excessive inflammation. Signaling occurs through two distinct mechanisms: intracellularly via nuclear translocation with SMAD3 and extracellularly after secretion and binding to its receptor, composed of IL18R1 and IL18RAP. IL-37 suppresses or reduces the production of pro-inflammatory cytokines, including IL1A, IL6, CCL12, CSF1, CSF2, CXCL13, IL1B, IL23A, and IL1RN, while sparing anti-inflammatory cytokines. It also inhibits dendritic cell activation. IL-37 interacts with SMAD3 and binds IL18R1, albeit with lower affinity than IL18, without acting as a receptor antagonist for IL18. Additionally, it forms a complex with the cargo receptor TMED10, facilitating translocation from the cytoplasm into the endoplasmic reticulum-Golgi intermediate compartment (ERGIC) and subsequent secretion.

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.

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
