Portable exhausters for use with XPert™ balance enclosures and weigh boxes, Precise™ HEPA-filtered glove boxes, and Protector™ XVS ventilation stations, demonstration hoods, and workstations. Exhausters use carbon and/or HEPA filters to remove hazardous powders, particulates, or vapors from the exhaust air stream, returning filtered air to the environment. No ducting to the outside is required.

PMA (Phorbol-12-Myristate-13-Acetate) is a diester of phorbol and is a tumor promoting compound extracted from croton oil. It is a reversible, highly potent protein kinase C (PKC) activator in vitro and in vivo at nM concentrations. PMA’s effects on PKC are attributed to its similarity to diacylgylerol, a natural activator of PKC.
PMA activates Ca2+- ATPase and potentiates forskolin-induced cAMP formation. It has been shown to inhibit apoptosis induced by the Fas antigen, but PMA induces apoptosis in HL-60 promyelocytic leukemia cells.
Potent tumor promoter; activates protein kinase C in vivo and in vitro.
Store at -20 °C. Protect from light.

DL-Dithiothreitol is also known as Clelands reagent; Protective agent for sulfhydryl groups (-SH). Quantitatively reduces disulfides (-S-S- to -SH). In this reaction the DTT is oxidized to the cyclic disulfide which ensures the reduction of other disulfides in solution. Disulfide reduction occurs quickly at pH 8.
Dithiothreitol is useful for stabilizing sulfhydryl containing enzymes. Effective in sample buffers for reducing protein disulfide bonds prior to SDS-PAGE. DTT can also be used for reducing the disulfide bridge of the cross-linker N,N'-bis(acryloyl)cystamine to break apart the matrix of a polyacrylamide gel. DTT is less pungent and is less toxic than 2-mercaptoethanol.
Useful for stabilizing sulfhydryl-containing enzymes.

β-NADP is a coenzyme necessary for the alcoholic fermentation of glucose and the oxidative dehydrogenation of other substances. It occurs widely in living tissue, especially in the liver. Nicotinic acid can be converted to nicotinamide in the body and, in this form, is found as a component of two oxidation-reduction coenzymes: nicotinamide adenine dinucleotide (NAD) and nicotinamide adenine dinucleotide phosphate (NADP). The nicotinamide portion of the coenzyme transfers hydrogens by alternating between oxidized quaternary nitrogen and a reduced tertiary nitrogen. NADP is an essential coenzyme for glucose-6-phosphate dehydrogenase which catalyzes the oxidation of glucose-6-phosphate to 6-phosphogluconic acid. This reaction initiates metabolism of glucose by a pathway other than the citric acid cycle. This route is known as the hexose phosphate shunt or phosphogluconate pathway. Other enzymes which utilize NADP as a coenzyme are: Alcohol dehydrogenase:NADP dependent; Aromatic ADH:NADP dependent; Ferredoxin-NADP reductase; L-Fucose dehydrogenase; Gabase; Galactose-1-phosphate uridyl transferase; Glucose dehydrogenase; L-Glutamic dehydrogenase; Glycerol dehydrogenase:NADP specific; Isocitric dehydrogenase; Malic enzymes; 5,10-Methylenetetrahydrofolate dehydrogenase; 6-Phosphogluconate dehydrogenase and Succinic semialdehyde dehydrogenase.
