[A modified method for labeling erythrocytes with 99mTc (author's transl)]. 1976

P Kleinert, and G Endert, and E Klose, and E Schumann

A modified method for labeling erythrocytes with 99mTc-sodium pertechnetate for spleenic scintigraphy is described. In vitro investigations have shown that by omitting the customary process of washing and by simultaneous alteration of the erythrocytes during the tin incubation period, the duration of erythrocyte labeling can be considerably reduced. A yield of 96 of 98% can be achieved. The effect of the tin on the erythrocytes is further investigated. The effect of the incubation period and temperature, of the plasma in the erythrocyte suspension, of stirring and agitation, of the dispersion liquid and tin concentration were studied. The method proves satisfactory in 56 controlled spleenic scintigrams.

D007553 Isotope Labeling Techniques for labeling a substance with a stable or radioactive isotope. It is not used for articles involving labeled substances unless the methods of labeling are substantively discussed. Tracers that may be labeled include chemical substances, cells, or microorganisms. Isotope Labeling, Stable,Isotope-Coded Affinity Tagging,Isotopically-Coded Affinity Tagging,Affinity Tagging, Isotope-Coded,Affinity Tagging, Isotopically-Coded,Isotope Coded Affinity Tagging,Labeling, Isotope,Labeling, Stable Isotope,Stable Isotope Labeling,Tagging, Isotope-Coded Affinity,Tagging, Isotopically-Coded Affinity
D010084 Oxidation-Reduction A chemical reaction in which an electron is transferred from one molecule to another. The electron-donating molecule is the reducing agent or reductant; the electron-accepting molecule is the oxidizing agent or oxidant. Reducing and oxidizing agents function as conjugate reductant-oxidant pairs or redox pairs (Lehninger, Principles of Biochemistry, 1982, p471). Redox,Oxidation Reduction
D004912 Erythrocytes Red blood cells. Mature erythrocytes are non-nucleated, biconcave disks containing HEMOGLOBIN whose function is to transport OXYGEN.
