Cayman Chemical DecnoIc AcIdodIum salt 25g

A medium-chain saturated fatty acid; a non-competitive antagonist at AMPA receptors; selectively reduces glutamate-induced currents in Xenopus oocytes expressing GluA2/3 subunit-containing AMPA receptors (IC50 = 0.52 mM) over those expressing GluA1 (IC50 = 2.09 mM) or GluA1/2 subunits (IC50 = 1.16 mM); inhibits epileptiform activity induced by pentylenetetrazole or low magnesium in rat hippocampal slices; induces contractions in isolated guinea pig duodenum at 1 mM; increases the escape threshold in an orofacial mechanical stimulation test in rats when administered as a 30% topical ointment; plasma levels of decanoic acid are increased in patients with colorectal cancer when compared to patients with breast cancer or ulcerative colitis or without cancer

Cole-Parmer Blue Tracer Dye Concentrate, 1gallon

Dyes diffuse rapidly in water, producing a vivid, easy-to-see color. Excellent for identifying diffusion and dispersion patterns, rates of flow, discharge locations, seepage areas, sea marking, and more. Use blue dye to brighten murky ponds and other landscaped waters. Minimum detectable concentration of all dyes in clear water is 1 ppm. Available in tablets, liquid, or powder. Quick dissolving tablets are easy to handling with less mess than other forms. They are perfect for applications such as storm lines, cooling and plumbing systems, and sewer lines. Choose liquid for applications such as metered input, flow/dilution/disperation rate assessment, septic inspections, or fluoremetric dye tests. Powder is well-suited for large applications where liquid is undesirable such a cooling towers, lakes, rivers, and ponds, or power plant piping.
