Evaluation of Glycosaminoglycans Biological Age in Cells and Tissues

Summary, in English

Bomb pulse refers to the sharp increase of the atmospheric levels of the carbon isotope
14C due to nuclear testing during the late 1950s and early 1960s. After the nuclear test ban, atmospheric
14C levels decreased exponentially because of the diffusion and equilibration with the ocean and biosphere, as well as the incorporation indirectly into all living cells. Thus, assessing the anthropogenic
14C serves as an isotopic chronometer providing the opportunity to estimate the age of a tissue and its components with a relatively high precision comparing it with the atmospheric levels at a certain time stamp.This protocol describes the use of the bomb pulse dating as a retrospective tracer of tissue components such as the glycosaminoglycans (GAGs) and subsequent proteoglycans turnover using accelerator mass spectrometry.
