Safranin O, also known as basic red 2, is a basic, cationic, and metachromatic azine dye used as a biological stain. The characteristic azine chromophore contains the phenazine, a planar, tricyclic dibenzopyrazine, which consists of two non-planar benzene rings linked by two nitrogen atoms. A delocalised positive charge, an alternation of aromatic and quinonoid structures, and diazotisable amine groups constitute the chromophoric system. c-Methylation makes this dye of moderate overall size. The trimethyl cationic form of safranine is lipophilic, whereas the dimethyl forms are weakly hydrophilic. The dye is commercially available as a chloride.

3-(2-Pyridyl)-5,6-di(2-furyl)-1,2,4-triazine-5′,5′′-disulfonic acid disodium salt, also known as Ferene, is commonly used to measure the concentration of iron ions in aqueous solutions. The reagent is sensitive to ferrous iron ions (Fe2+) and forms a purple-colored complex with these ions in the presence of a reducing agent. The intensity of the purple color formed is proportional to the concentration of iron ions present in a solution and is quantified spectrophotometrically.

Avantor® ACE® UltraCore SuperC18 solid core (core shell) particle columns are ideal for demanding MS work offering improved MS signal intensity and maximum MS response. These stainless steel columns combine high efficiency separations with low column back pressure. The Encapsulated Bonding Technology (EBT™) greatly increases the ligand coverage of the silica surface and effectively eliminates the effect of unbonded silanol groups on separations. This higher ligand coverage results in improved inertness, chromatographic performance and stability.

HMGB1 was originally discovered as an essential DNA-binding protein for regulating p53, NF-kappaB and other important proteins. It is secreted from activated dentric cells, macrophage and nectrotic cells, and acts as a ligand for RAGE, TLR-2 and TLR-4 expressed on surrounding cells. As a result, HMGB1 activates Rac, CDC42 and NF-kappaB inducing localised innate immunity of damaged tissue, tissue regeneration by recruitment of stem cells and hemostasis by induction of tissue factor expression. HMGB1 is also causative agent of various diseases as it causes localised inflammation such as arteriosclerosis, chronic rheumatoid arthritis and nephritis.

IGF2BP1 is a member of the insulin-like growth factor 2 mRNA-binding protein family. The protein encoded by this gene contains four K homology domains and two RNA recognition motifs. It functions by binding to the mRNAs of certain genes, including insulin-like growth factor 2, beta-actin and beta-transducin repeat-containing protein, and regulating their translation. Two transcript variants encoding different isoforms have been found for this gene.

Leukemia inhibitory factor (LIF) is a member of the interleukin 6 (IL-6) family that is made by a variety of adult and embryonic tissues. LIF signals through the glycoprotein 130 (gp130)/LIF receptor (LIFR) heterodimer to activate STAT3 and MAPK signaling. LIF functions during hematopoietic differentiation, neuronal cell differentiation, kidney development, and inflammatory processes. Human LIF may also be an important factor during human embryonic stem cell (hESC) self-renewal, pluripotency, and embryonic implantation.

Supplier: Shenandoah Biotechnology

Interleukin 17F (IL-17F), a member of the IL-17 cytokine family, is secreted by activated CD4+ T cells and monocytes. IL-17F binds the IL-17 receptor related molecule, IL17RC, to promote the production of the interleukin 6 (IL-6), interleukin 8 (IL-8), and granulocyte macrophage colony-stimulating factor (GM-CSF) cytokines. IL-17F also functions to regulate matrix turnover rates, inhibit endothelial cell angiogenesis, and induce the endothelial cell expression of interleukin 2 (IL-2), monocyte chemoattractant protein-1 (MCP-1), and transforming growth factor beta 1 (TGF-β1).
