Conjugate | Avi-tag Biotinylated E. coli biotin ligase (BirA) is highly specific in covalently attaching biotin to the 15 amino acid AviTag peptide. This recombinant protein was biotinylated in vivo by AviTag-BirA technology, which method is BriA catalyzes amide linkage between the biotin and the specific lysine of the AviTag. |

This IL-8 (CXCL8) protein is a semi-custom product. There are 5 expression system options: Yeast, E. coli, In Vivo Biotinylation in E. coli, Baculovirus, and Mammalian cell. Your requirements will be given top priority in determining the protein tags. For proteins within 800 aa, risk-free custom service is guaranteed. It means you will not be charged if the protein cannot be delivered.
IL-8, also called CXCL8, is a chemokine crucial in various physiological and pathological processes. Initially recognized for its leukocyte chemotactic properties, CXCL8 has been found to have tumorigenic and proangiogenic effects [1]. It acts as a multifunctional cytokine influencing tumor proliferation, invasion, and migration in both autocrine and paracrine manners [2]. CXCL8 mediates its activities by binding to two G protein-coupled receptors, CXCR1 and CXCR2 [3].
CXCL8 promotes tumor proliferation, migration, and invasion [4]. It is a potent chemoattractant for neutrophils, myeloid-derived suppressor cells (MDSCs), and monocytes, which are components associated with immunosuppression in cancer [5]. CXCL8 regulates dendritic cell activation markers and recruitment, indicating its role in the immune response against colorectal cancer [5].
For inflammatory responses, CXCL8 is known to guide neutrophils through tissue matrices to injury sites, showcasing its role as a potent chemoattractant molecule [6]. Furthermore, CXCL8 has been linked to neutrophil recruitment, activation, and the release of neutrophil extracellular traps (NETs) in severe COVID-19 cases, contributing to inflammation and organ dysfunction [7].
