Kinetics of Iodination

Iodination of Tyrosyls in Thyroglobulin

Towards graphene iodide: iodination of graphite oxide.

Halogenated graphene derivatives are interesting owing to their outstanding physical and chemical properties. In this paper, we present various methods for the synthesis of iodinated graphene derivatives by the iodination of graphite oxides prepared according to either the Hummers or Hofmann method. Both graphite oxides were iodinated by iodine or hydroiodic acid under reflux or in an autoclave...

Iodination of Bacteria: a Bactericidal Mechanism

Myeloperoxidase, iodide, and H(2)O(2) have a bactericidal effect on Escherichia coli. Myeloperoxidase can be replaced in this system by lactoperoxidase or by a guinea pig leukocyte particulate preparation, H(2)O(2) by an H(2)O(2)-generating system such as glucose and glucose oxidase, and iodide by thyroxine or triiodothyronine. The bactericidal effect was high at pH 5.0 and fell as the pH was i...

Iodination of annexin V for imaging apoptosis.

UNLABELLED Our goal in this investigation was to develop a method for iodinating annexin V that would be suitable for the in vivo detection of apoptosis. METHODS Annexin V was iodinated with (125)I using 2 different techniques: direct iodination with IODO-BEADS, resulting in the iodination of tyrosine residues; and use of the Bolton-Hunter reagent, which binds to lysine. The active fraction o...

Enzymatic iodination of Sindbis virus proteins.

Sindbis virus was iodinated by using the enzyme lactoperoxidase, an iodination technique which labels only surface proteins. By this technique, the two viral glycoproteins are labeled, and the internal viral protein is not. The two glycoproteins are iodinated to strikingly different extents. This difference in susceptibility to iodination apparently is due to the position or conformation of the...
