Half-LifeReference work entry pp 897 Cite this reference work entry Encyclopedic Dictionary of Polymers Jan W. Gooch 44 Accesses For a chemical reaction, the time at which half the substrate has been consumed and turned into product. The term can also refer to the analogous point in other...
For a given reaction the half-life, t1/2, of a reactant is the time required for its concentration to reach a value that is the arithmetic mean of its initial and final (equilibrium) value.

to measure the terminal half-life of each protein. Male cynomolgus monkeys (four per group) were used to assess the PK of the XTEN1–rhGH and VRS-317 after a single s.c. dose of 5 mg/kg XTEN1–rhGH (44.1 nmol/kg) or VRS-317 (42.1 nmol/kg). The plasma samples were taken at ...
