Description

A unique combination of a number of proprietary plasmids digested with appropriate restriction enzymes and PCR products to yield 13 fragments, suitable for use as molecular weight standards for agarose gel electrophoresis. The DNA includes fragments ranging from 250-10,000 base pairs. The 1K and 3K bands have increased intensity to serve as reference points. The approximate mass of DNA in each band is provided (0.5 μg a load) for approximating the mass of DNA in comparably intense samples. The ladder is ready-to-use, and is premixed with loading buffer dye for direct loading on gel.

Description

1,2-Dimyristoyl-rac-glycerol is a carboxylic ester, glycerolipid and diglyceride with an attached myristoyl group, promoting interactions between proteins and lipids. It can be employed as a detergent or reagent. It’s functional in cell biology experimentation concerning metabolism and metabolic pathways involving glycerolipids.

As a diglyceride, the substance consists of two fatty acid chains covalently bonded to the glycerol molecule in the 1,2- formation. Diglyceride (DAG) research investigates the process of suppressing fat accumulation through DAG consumption.

Description

1,2-Dipalmitoyl-rac-glycero-3-phosphocholine is a phospholipid with two palmitic acids and is the racemic mixture of Dipalmitoylphosphatidylcholine (also known as Colfosceril palmitate or DPPC). The phosphocholine head is sensitive to electric charges at the membrane surface when bound to pure phospholipids. When added to a solution containing charged ions, this sensitivity can shift the nitrogen cation away from a lack of positive charge or towards a positive charge in solution. In a research environment, it is useful in studying changes of biological membranes and liposomes. Because of its ability to form simple phospholipid bilayers, it is useful in computer modeling of bilayers in dynamic situations. Modeling can also be extended to interactions between DPPC and other biologically active molecules (like pharmaceuticals) as an analog for the same naturally occurring process. It is also useful in the formation of reconstituted HDL particles.

Description

1,2-Dipalmitoyl-sn-glycero-3-phosphoethanolamine or DPPE is a phospholipid component of the cell membrane. It is used in membrane models and is part of the glycerophosphoethanolamine family. DPPE has been shown to cause competitive hydrogen bonding of amine groups with phosphate/carbonyl groups or water. Additionally, DPPE has been studied along with cholesterol, showing cholesterol’s ability to induce DPPE monolayer condensation when calcium ions are present.

Description

2-Deoxy-D-glucose is a molecule with a broad range of applications, from a reagent to a potential anti-cancer drug. As a reagent it can be combined with the radiolabel fluorine-18 to monitor glucose metabolism using positron emission tomography (PET) allowing detection of altered metabolism resulting from diseases like Alzheimer’s and cardiovascular disease. As a therapeutic drug 2-Deoxy-D-glucose uptake is the same as regular glucose, but has an inhibiting effect on cell growth. This makes it an effective tumor suppressant. It is a potential anti-epileptic drug due to its mimicry of ketogenic diets used for treating epilepsy, by increasing Brain-derived neurotrophic factors, nerve and basic fibroblast growth factors and Arc protein. 2-Deoxy-D-glucose’s anti-cancer properties stem from its ability to slow both tumor growth and mark tissues with elevated glucose and hexokinase activity, which are common markers for cancer activity. It can also be used to increase the absorption of other chemotherapy agents like adriamycin and paclitaxel.

Description

3,5-Dichloro-2-hydroxybenzenesulfonic acid, disodium salt is a reagent used to produce peroxides when combined with 4-aminoantipyrine. It is also used in quantification of hydrogen peroxide through horseradish peroxidase-mediated conversion of itself and 4-aminoantipyrine to a colored product. Under this principle, it is used to determine uric acid in serum as oxidation of uric acid in a uricase-catalyzed reaction yields hydrogen peroxide.
