Cayman Chemical MethIonIn SulfoxID Imunobl 1ea
Protein MetO is a reversible oxidative modification that occurs by exposure of protein(s) methionine residues to reactive oxygen species (ROS). Methionine oxidation can alter the function(s) of the modified proteins and if not reversed by MetO reductases can be further oxidized to methionine sulfone, an irreversible modification. Cayman’s MetO Immunoblotting Kit contains reagents needed for the immunochemical detection of proteins containing MetO residues by western blotting. MetO-containing samples of interest include those from cell or tissue lysates as well as semi-pure or purified proteins.

Alkali Scientific Moeller Decarboxylase Broth w/Ornithine 5mL Tube, 10/Pk
Moeller Decarboxylase Broth with Ornithine is a biochemical medium used to determine whether microorganisms produce the enzyme ornithine decarboxylase. The test is frequently used for differentiation of Gram negative enteric bacteria such as Enterobacter, Klebsiella, and Proteus species. Each 5 mL tube contains glucose, peptones, the amino acid ornithine, and pH indicators including bromocresol purple and cresol red. After inoculation, organisms ferment glucose and create an acidic environment that turns the medium yellow. If the organism possesses ornithine decarboxylase, the enzyme converts ornithine into the alkaline compound putrescine. This raises the pH and changes the medium back to purple. When the enzyme is absent, the medium remains yellow, indicating a negative reaction useful for biochemical identification.
