Glutathione is the major low molecular weight thiol compound of the living plant or animal cell. It is a tripeptide with a gamma peptide linkage between the amine group of cysteine (which is attached by normal peptide linkage to a glycine) and the carboxyl group of the glutamate side-chain. It is an antioxidant, preventing damage to important cellular components caused by reactive oxygen species such as free radicals and peroxides. The sulfhydryl (thiol) group (SH) of cysteine serves as a proton donor and is responsible for the biological activity of glutathione.
Glutathione suppresses human immunodeficiency virus expression in chronically infected monocytic cells. It is a useful tripeptide involved in many aspects of metabolism, including transport of g-glutanyl amino acids and reductive cleavage of disulfide bonds.
Endogenous antioxidant that plays a major role in reducing reactive oxygen species formed during cellular metabolism and the respiratory burst. Glutathione-S-transferase catalyzes the formation of glutathione thioethers with xenobiotics, leukotrienes, and other molecules that have an electrophilic center. Glutathione also forms disulfide bonds with cysteine residues in proteins. Via these mechanisms, it can have the paradoxical effect of reducing the efficacy of anti-cancer agents.

Monokine induced by interferon-gamma (MIG), or CXCL9, is a member of the CXC chemokine family. MIG is closely related to two other chemokines: CXCL10 and CXCL11, all of which signal through the CXCR3 receptor (Ding et al.). MIG is secreted by a variety of immune cells including T cells, NK cells, dendritic cells, macrophages, and eosinophils, as well as non-immune cells including hepatic stellate cells, preadipocytes, thyrocytes, endothelial cells, tumor cells, fibroblasts, and glial cells of the central nervous system. MIG has also been shown to act as a chemoattractant for activated T cells and for tumor-infiltrating leukocytes (TILs), but not for neutrophils or for monocytes. MIG has also been reported to be both a tumor suppressor and tumor promoter in various types of cancer.

Dimethyl Sulfoxide is ideal for use as a cryoprotectant. Also used in chemical reactions, in polymerase chain reactions (PCR) as a PCR cosolvent to help improve yields, especially in long PCR, and as a cryoprotectant vitrification agent for the preservation of cells, tissues and organs. DMSO is used in cell freezing media to protect cells from ice crystal-induced mechanical injury. It is used for frozen storage of primary, sub-cultured, and recombinant heteroploid and hybridoma cell lines, embryonic stem cells (ESC), and hematopoietic stem cells. DMSO is frequently used in the combinations with BSA or fetal bovine serum (FBS). Used to enhance dermal absorption of many chemicals. A solvent for many organic and inorganic compounds including fats, carbohydrates, dyes, resins, and polymers. Used in antifreeze or hydraulic fluids. A cryopreservative for cell cultures. Used in the oxidation of thiols and disulfides to sulfonic acids.

Dimethyl sulfoxide (DMSO) is a highly polar aprotic organic reagent that has exceptional solvent properties for organic and inorganic chemicals.

Fibroblast growth factor 4 (FGF-4) is a member of the FGF superfamily (Beenken and Mohammadi). FGF-4 is expressed in pluripotent stem cells and is implicated in various stages of development and morphogenesis in a variety of organisms (Kosaka et al. 2009). FGF-4 has been shown to have an ability to promote neural stem cell proliferation and neuronal differentiation in the postnatal brain (Kosaka et al. 2006). FGF-4 has also been shown to increase the proliferation rate of mesenchymal stem cells (Farré et al.). FGF-4 supports the maintenance and self-renewal properties of human embryonic stem cells and also promotes the proliferation of these cells (Mayshar et al.). In the mouse, the Fgf4 gene also supports proliferation of the inner cell mass (ICM) and postimplantation embryos (Feldman et al.).
