Cultures from old donors produced less T cell growth factor (TCGF) and incorporated less tritiated thymidine
(3H-Tdr) than did similar cultures from young donors in the presence of either mitogen.
(19,20) In a prior study, (21) using tritiated thymidine
labeling to identify S-phase cells, evidence of regional variation within breast carcinomas was detected in 61% of 50 tumors.
We were interested in examining the relationship between a woman's age and micronutrient deficiency status and how these factors contribute to an individual's overall immune function using two different measurements: their lymphocyte's antioxidant function (as measured by the ability of their lymphocytes to handle an oxidative challenge by treating the cells with hydrogen peroxide) and the overall ability of their lymphocytes to grow and proliferate (which we measured using a method called tritiated thymidine
incorporation, which is a standard approach in immunoassays).
Using a tritiated thymidine
assay, dose-dependent DNA synthesis inhibition was seen as early as 2 hours after treatment.
Catabolism of tritiated thymidine
by aquatic microbial communities and incorporation of tritium into RNA and protein.
The cells used for the evaluation was human umbilical vein endothelial cells (HUVEC) and the proliferation rate of these cells on drug coated stent was compared against an uncoated stent made of the same base material as measured by the tritiated thymidine
uptake of cells grown on these devices for period of 72h.
We obtained auricular LN cells and PBMC for each exposure group 48 hr after the final application of chemical, and the lympho-proliferative response was measured by tritiated thymidine
incorporation at designated time points.
Virus production rates have also been estimated directly, by three independent methods: (a) tritiated thymidine
incorporation into viral DNA (Steward et al., 1992), (b) dilution of fluorescently labeled viruses added to trace production and loss (Noble and Fuhrman, 2000), and (c) virus increase in samples filtered to reduce viral abundance (Wilhelm et al., 2002).
First, the determination of bacterial secondary production from incorporation rates of tritiated thymidine
or leucine, requires itself the adoption of several conversion factors.
Hughes (Proc Natl Acad Sci) explain the organization and duplication of chromosomes using autoradiography with tritiated thymidine
The incubation medium contains tritiated thymidine
. As the cells proliferate, the tritiated thymidine
is taken from the medium by the dividing cells and incorporated into their genetic material.
