DDX25 is a member of DEAD box proteins family. DEAD box proteins, characterized by the conserved motif Asp-Glu-Ala-Asp (DEAD), are putative RNA helicases. They are implicated in a number of cellular processes involving alteration of RNA secondary structure, such as translation initiation, nuclear and mitochondrial splicing, and ribosome and spliceosome assembly. Based on their distribution patterns, some members of the DEAD box protein family are believed to be involved in embryogenesis,spermatogenesis, and cellular growth and division. DDX25 is a gonadotropin-regulated and developmentally expressed testicular RNA helicase. It may serve to maintain testicular functions related to steroidogenesis and spermatogenesis.DEAD box proteins, characterized by the conserved motif Asp-Glu-Ala-Asp (DEAD), are putative RNA helicases.

MP EcoChrom™ SILICA is used as a suspending and thickening agent in pharmaceutical.A silica-based aerogel was used in the Stardust spacecraft to collect extraterrestrial particles. Silica is also used in the extraction of DNA and RNA due to its ability to bind to the nucleic acids under the presence of chaotropes. As hydrophobic silica it is used as a defoamer component. In hydrated form, it is used in toothpaste as a hard abrasive to remove tooth plaque. SiO2 has a number of distinct crystalline forms (polymorphs) in addition to amorphous forms. In the majority of silicates, the Si atom shows tetrahedral coordination, with 4 oxygen atoms surrounding a central Si atom.

MP EcoChrom™ Silica, the chemical compound silicon dioxide, also known as silica (from the Latin silex), is an oxide of silicon with the chemical formula SiO2 with a mean pore size of 60Å and particles size of 200-500μm. MP silica are free of particles outside the standard range. The irregular shape of MP Silica permits the easy packing of column permeability and plate number. They allow easy switching from one sieve cut to another, offering an easy way to change the chromatographic methods. It has been known for its hardness since ancient times. Silica is most commonly found in nature as sand or quartz, as well as in the cell walls of diatoms.

Lupeol, a dietary triterpene found in certain fruits, vegetables, and medicinal plants, has potent anti-inflammatory, anticarcinogenic, antimutagenic, and antimalarial activity. It suppresses the growth of hepatocellular carcinoma cell lines SMMC7721 and HepG2 with IC50 values of 45 and 48.5 μM and melanoma cell lines Mel 928 and Mel 1241 with IC50 values of 75 and 72 μM.¹'² At 0.76 g/kg lupeol causes a significant decrease in the blood pressure of stroke-prone hypertensive rats and reduces expression of hepatic genes involved in triglyceride and cholesterol synthesis.³ It also has significant anti-inflammatory effects at 50 mg/kg in a carrageenan-induced edema model, inhibiting neutrophil migration.⁴

Slide-A-Lyzer MINI Dialysis devices, 3,5K MWCO, are disposable polypropylene cups with integrated, low-binding membranes for dialysis and high recovery of proteins and macromolecules >3,5 kDa in volumes from 10 µl to 2 ml. They were developed as a convenient means for dialysing small-volume samples of nucleic acids and proteins without undue sample loss. Low molecular weight contaminant removal, buffer exchange, desalting, equilibrium dialysis, micro conjugation reactions, and concentration can be accomplished with these devices.

Hemagglutinin Monoclonal Antibody: Influenza A virus is a major public health threat, killing more than 30,000 people per year in the USA. Novel influenza virus strains caused by genetic drift and viral recombination emerge periodically to which humans have little or no immunity, resulting in devastating pandemics. Influenza A can exist in a variety of animals, but it is in birds that all subtypes can be found. These subtypes are classified based on the combination of the virus coat glycoproteins hemagglutinin (HA) and neuraminidase (NA) subtypes. HA interacts with host cell surface proteins containing oligosaccharides with terminal sialyl residues. Its extracellular region has two domains (HA1 and HA2); HA1 is cleaved from the main hemagglutinin protein by the host immune system. During 1997, an H5N1 avian influenza virus was determined to be the cause of death in 6 of 18 infected patients in Hong Kong. This more recent virulent strain of H5N1 is now seen in Africa and Europe, as well as in Southeast Asia. There is some evidence of human to human spread of this virus, but it is thought that the efficiency of this type of transmission is low. Virus isolated from a human infected with the H5N1 strain in 1997 could bind to oligosaccharides from human as well as avian sources, indicating its species-jumping ability.

Recently, a number of cytokines belonging to the interleukin (IL)-17 family have been identified. These are termed as IL-17B, IL-17C and IL-17E. IL-17 is a potent proinflammatory cytokine that plays roles in a number of diseases including rheumatoid arthritis , multiple sclerosis , and promotion of tumor growth. IL-17B, C, and E like IL-17 are able to induce proinflammatory responses. However, they do not bind to the IL-17 receptor suggesting that additional IL-17R related receptor might exist. Receptor for IL-17B and IL-17E has been independently isolated by Shi, et al and Lee, et al. and has been designated as EV127 (in mouse) and IL-17Rh1 (in human), respectively. IL-17E induces activation of NF-κB pathway and like IL-17 also induces production of IL-8. The IL17 proteins are a family of potent cytokines that act to induce proinflammatory responses. Studies have shown that IL17E binds strongly to IL17RB. Receptor binding of ligand has been shown to lead to the activation of nuclear factor kappa-B and production of IL8. Exposure of mice to IL17 resulted in a Th-2 like response characterized by increased serum IgE, IgG1 and IgA levels, blood eosinophilia, increased lymphocytes and neutrophils, and pathological changes in the tissues that included eosinophilic infiltrates, increased mucus production, B-lymphocyte hyperplasia and epithelial cell hyperplasia/hypertrophy.

In order to maintain cellular viability during the freezing process, certain cells such as protist, mammalian, and plant cells require precise control of the freezing rate in order to minimize the detrimental effects of undercooling and the heat liberated during the phase change process from water to ice. The Thermo Scientific™ CryoMed™ Controlled-Rate Freezers (CRFs) are designed with reliability, protection, and data traceability in mind for sample preparation and GMP production needs.

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.
