Receptor activator of nuclear factor kappa-B ligand (RANKL) is a member of the tumor necrosis factor (TNF) superfamily (Anderson et al.). Cytokines in the TNF superfamily are involved in a variety of long-term cellular activities such as differentiation, proliferation, and cell death (MacEwan). RANKL is a type II homotrimeric transmembrane protein expressed in both a membrane-bound and secreted form (Ikeda et al.). RANKL binds to the receptor activator of nuclear factor kappa-B (RANK). Upon binding to its receptor, RANKL activates the AKT signaling pathway (Moon et al.). Osteoprotegerin (OPG) may also bind RANKL, and this binding competes with RANKL-RANK binding (Lacey et al.). RANKL is involved in osteoclastogenesis (Lacey et al.; Yasuda et al.) and T cell activation (Wong et al.). This product is animal component-free.

Monocyte chemotactic protein-1 (MCP-1), also known as CCL2, is a member of the CC family of chemokines. The protein is primarily induced by platelet-derived growth factor (PDGF) gene (Cochran et al.). The biological effects of MCP-1 are mediated via the specific G-protein-coupled receptor CCR2 which in turn activates signal transduction pathways leading to monocyte transmigration (Sozzani et al.). Migration of monocytes from the bloodstream across the vascular endothelium is required for routine immunological surveillance of tissues, as well as other immunomodulatory effects. MCP-1 is produced by a variety of cell types, including fibroblasts and endothelial, epithelial, smooth muscle, mesangial, astrocytic, monocytic, and microglial cells, which are important for antiviral responses in the peripheral circulations and in tissues (Cushing et al.; Deshmane et al.). MCP-1 plays a role in physiological processes such as neurogenesis, neuroprotection, and neurotransmission and has important implications in neurological disorders such as multiple sclerosis and Alzheimer’s disease, in which it is produced during neuroinflammation at the sites of lesions (Conductier et al.).

Interleukin 10 (IL-10) is the founding member of the IL-10 family of class II cytokines. All of the IL-10 cytokine family members have a four-helix bundle consisting of α-helical folds. Upon binding to its receptor, IL-10 activates signaling through JAK1 and STAT3. It is produced by dendritic cells, macrophages, and CD4+ T regulatory cells, as well as mast cells, NK cells, neutrophils, and regulatory B cells, under specific stimulating conditions (Saraiva and O'Garra). IL-10 can inhibit the activation of certain immune cells while it promotes the function of B cells, and facilitate healing process. Specifically, this cytokine is important for the function of T regulatory cells as it is a potent suppressor of effector T cell proliferation and cytokine production. Also, IL-10 produced by a subset of macrophages inhibits activation and production of pro-inflammatory cytokines by neighboring macrophages, thus allowing a level of self-regulation. IL-10 enhances B cell proliferation, immunoglobulin secretion, and class II MHC expression (Ouyang et al.).

Butyrophilin 1A1 (BTN1A1) is a glycoprotein belonging to the butyrophilin (BTN) family which collectively modulates immune responses, through excitatory and inhibitory signals targeting immune cells. Butyrophilins are composed of two extracellular immunoglobulin domains and a transmembrane region, with a conserved B30.2 domain (PRYSPRY) that is present in most members (Malinowska et al.). BTN1A1, along with BTN2A2, has been shown to inhibit the proliferation of CD4+ and CD8+ T cells, modify T cell metabolism, and affect the expression of IL-2 and IFN-γ (Smith et al.). Due to these modulatory effects on T cells, BTN1A1 may have a role in inhibiting the development of autoimmune diseases (Stefferl et al.). BTN1A1 is also expressed in mammary glands and is required for the secretion of milk lipids during lactation (Ogg et al.). This protein contains a His-residue tag at the carboxyl end of the polypeptide chain. For consistency and reproducibility across your applications, Serpin A12 from STEMCELL comes lyophilised with ≥92% purity, and is verified by LAL analysis to ensure endotoxin levels are ≤1,0 EU/μg protein.
