The luminescent oxygen channeling immunoassay (LOCI) generates singlet oxygen species in microbeads coupled to the analyte, and when the analyte binds to the respective Ab molecule, coupled to another kind of bead, the analyte reacts with singlet oxygen, generating chemiluminescence signals proportional to the concentration of the analyte-Ab ...
Recently, singlet oxygen has been found to be a source of biologically-produced ozone: This reaction proceeds through an unusual compound dihydrogen trioxide, also known as trioxidane, (HOOOH), which is an antibody-catalyzed product of singlet oxygen and water. This compound, in turn, disproportionates to ozone and peroxide, providing two ...
Parts-per-million cube of relative abundance by mass of elements in an average adult human body down to 1 ppm. About 99% of the mass of the human body is made up of six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus. Only about 0.85% is composed of another five elements: potassium, sulfur, sodium, chlorine, and magnesium ...
EMIT therapeutic drug monitoring tests provide accurate information about the concentration of such drugs such as immunosuppressant drugs and some antibiotics. [ 3 ] [ 4 ] EMIT urine assays for drugs such as cannabinoids, morphine, and amphetamine are designed to detect the drug itself or a metabolite of the drug present in a concentration ...
In practice, for both practical and safety reasons, almost all recent applications of the "doubly labeled water" (DLW) method use water labeled with heavy but non-radioactive forms of each element (deuterium, 2 H; and oxygen-18, 18 O). In theory, radioactive heavy isotopes of the elements could be used for such labeling; this was the case in ...
The alkali metals and alkali earth metals all react spontaneously with oxygen when exposed to dry air to form oxides, and form hydroxides in the presence of oxygen and water. As a result, none of these elements is found in nature as a free metal. Caesium is so reactive with oxygen that it is used as a getter in vacuum tubes. Although solid ...
It is imperative that the binding of the fluorophore to the antibody itself does not interfere with the immunological specificity of the antibody or the binding capacity of its antigen. [ 4 ] [ 5 ] Immunofluorescence is a widely used example of immunostaining (using antibodies to stain proteins) and is a specific example of immunohistochemistry ...
