  • For quantitative determination of ammonia/ammonium concentration. Linear detection range 24 to 1000 μM ammonia. Simple "mix-and-measure" type assay. Method: OD340 nm, or FL360/450 nm. Samples: Serum, plasma, urine, saliva, cell culture etc.

  • UltraPure Water

    Cayman Chemical

    Water used for the preparation of EIA reagents and buffers.

  • The Better BCA Assay Kit can be used for quantitation of total protein in samples while minimizing interference from disulfide reducing agents. The BCA assay is based on the well-known reduction of Cu2+ to Cu+ 

  • Most histone lysine methyltransferases contain a conserved domain (SET) that utilizes S-adenosyl-L-methionine (SAM or AdoMet) as a co-factor to catalyze the methylation of lysine. SET7/9 (KMT7) is a SET domain-containing mono-methyltransferase that acts on a large number of histone and non-histone…

  • Bradford method utilizes Coomassie Brillant Blue G-250 dye binding to an unknown protein and forming a complex which can be detected spectophotometrically at 595 nm. This kit is designed to quantitate 10-150 µg/ml of protein.

  • Deionized Water

    BioAssay Systems

    Deionized water used for preparation of samples for use with the QuantiQuik™ UreaQuick Test Strips .

  • Cayman’s Lipid Droplets Fluorescence Assay Kit can be used to study regulators of lipid droplet biogenesis. The main advantage of this assay is that the green fluorescence of Nile Red is both very sensitive and specific for lipid droplets. Furthermore, changes in lipid droplet biogenesis in…
