| Description | 3x DYKDDDDK Tag is a useful tool for investigating the function and localization of proteins whose antibodies (Abs) are not available. Often it is also used in a 3X FLAG format (3x DYKDDDDK Tag) for purifying difficult proteins that accumulate in low abundance [1][2] | Charybdotoxin TFA, a 37-amino acid peptide, is a K+ channel blocker[1] | Endomorphin 1, a high affinity, highly selective agonist of the µ-opioid receptor (Ki: 1.11 nM), displays reasonable affinities for kappa3 binding sites, with Ki value between 20 and 30 nM. Endomorphin 1 has antinociceptive properties[1][2][4] | Leucine dehydrogenase, Microorganism (EC 1.4.1.9) can be purified from Bacillus spheroides. Leucine dehydrogenase catalyzed the oxidative deamination of L-leucine, L-valine, L-isoleucine, L-norvaline, L-alpha-aminobutyrate, and L-norleucine, and the reductive amination of their keto analogues[1] | Pyruvate Oxidase, Microorganisms (PoxB) is a thiamine pyrophosphate-dependent oxidase that catalyzes the oxidative decarboxylation of pyruvate to acetyl phosphate, carbon dioxide and water. Pyruvate oxidase is an important enzyme in bacterial metabolism and is often used in biochemical research[1] |
