Animal-Free IL-8/CXCL8 Protein, Human (His)

Cat. No.: HY-P700133AF
COA Handling Instructions

IL-8/CXCL8 protein, a vital chemotactic factor, orchestrates inflammatory responses by attracting neutrophils, basophils, and T-cells to clear pathogens. It activates neutrophils and binds to CXCR1/CXCR2 receptors, initiating downstream signaling pathways. IL-8/CXCL8 homodimerizes, disrupted by tick evasin-3, and interacts with TNFAIP6, potentially regulating chemokine activity in the inflammatory microenvironment. Animal-Free IL-8/CXCL8 Protein, Human (His) is the recombinant human-derived animal-FreeIL-8/CXCL8 protein, expressed by E. coli , with C-His labeled tag. The total length of Animal-Free IL-8/CXCL8 Protein, Human (His) is 72 a.a., with molecular weight of ~9.32 kDa.

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

Background

IL-8/CXCL8 protein serves as a pivotal chemotactic factor, playing a central role in mediating inflammatory responses by attracting neutrophils, basophils, and T-cells to effectively clear pathogens and protect the host from infections. It also contributes significantly to neutrophil activation. Released in response to inflammatory stimuli, IL-8/CXCL8 exerts its effects by binding to G-protein-coupled receptors CXCR1 and CXCR2, primarily found in neutrophils, monocytes, and endothelial cells. The G-protein heterotrimer (alpha, beta, gamma subunits) constitutively binds to CXCR1/CXCR2 receptors, and activation by IL-8 leads to the release of beta and gamma subunits from Galpha (GNAI2 in neutrophils) and subsequent activation of downstream signaling pathways, including PI3K and MAPK pathways. IL-8/CXCL8 forms homodimers, and this dimerization is disrupted by tick evasin-3. Furthermore, IL-8/CXCL8 interacts with TNFAIP6 via its Link domain, and this interaction interferes with chemokine binding to glycosaminoglycans, suggesting a regulatory role in modulating chemokine activity within the inflammatory microenvironment.

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
