Thromboplastin as a Reagent

Thrombosis and Haemostasis, 1970
SummaryTissue thromboplastin is the key reagent in the one-stage prothrombin time test. To obtain reliable results, a potent thromboplastin with constant activity and stability is required. This need is met by acetone-dehydrated rabbit brain. This reagent, when protected against oxidation by sealing in an evacuated tube, retains its full activity ...

The reagents

1980
Publisher Summary The principle of the fluorescent antibody technique is based on the fact that in an antigen–antibody reaction the antibody becomes bound to its homologous antigen. If an antibody is labeled with a fluorescent dye that can be made visible by excitation with an appropriate light wavelength, then the site where the antibody reacts with ...

Mechanistic studies on the Rh(III)-mediated amido transfer process leading to robust C-H amination with a new type of amidating reagent.

Journal of the American Chemical Society, 2015
Mechanistic investigations on the Cp*Rh(III)-catalyzed direct C-H amination reaction led us to reveal the new utility of 1,4,2-dioxazol-5-one and its derivatives as highly efficient amino sources.
