Supplier: ProSci Inc.

IDO catalyzes the first and rate-limiting step in the main pathway of human tryptophan catabolism, the kynurenine pathway. Proinflammatory mediators, such as endotoxin and IFN-gamma induce the expression of IDO in several tissues. IDO-dependent suppression of T-cell responses might function as natural immunoregulatory mechanism. Physiological IDO activity has been implicated in T-cell tolerance to tumors, dysfunctional selftolerance in non-obese diabetic (NOD) mice, and as a protective negative regulator in autoimmune disorders.

These irrigating buffers and salt solutions are sterile, physiological balanced solutions intended for use in the maintenance of mammalian cells, where a chemically defined, balanced salt solution provides an environment that will maintain the structural and physiological integrity of cells in vitro. Applications include the intermediate steps for cultivation of cells, like washing, centrifugation, suspending and counting, as well as for many analytical methods or biochemical treatments. Principally these solutions should be used to keep the cells in suspension only for minutes or a few hours maximum. These buffers and solutions are not cell culture media.

Supplier: Biotium

Phalloidin is a toxin isolated from the deadly Amanita phalloides mushroom. It is a bicyclic peptide that binds specifically to F-actin. Fluorescent conjugates of phalloidin are convenient tools to investigate the distribution of F-actin in fixed and permeabilised cells or tissue sections. One unit (U) of phallodin is sufficient to stain one sample (200 µl staining volume). A highly selective actin filament stain for fixed and permeabilised cells. Labeled phalloidins have similar affinity for both large and small filaments.

Micro-quartz filters are useful for testing hot "stack" gases as the quartz fibers can withstand temperatures up to 900 °C. In addition, micro-quartz is used when the highest purity media is required. With excellent filtration properties and minimal traces of metals and minerals, quartz fibers are dimensionally stable and can be used in the analysis of acidic gases with the exception of hydrofluoric acid.
