carrier-free

 [kar´e-er-fre″]
a term denoting a radioisotope of an element in pure form, i.e., essentially undiluted with a stable isotope carrier.

Unfortunately, the reactor produced rhenium-186 is a carrier added radionuclide with lower specific activity, due to the presence of cold rhenium-185 excess, compared to the generator produced rhenium-188 that is instead carrier-free and available from an in-house generator system similar to the technetium-99m one currently in wide use.
[13-15] demonstrated that this method could be easily adaptable to an instant "kit" for carrier-free rhenium-188 radiolabeling of antibodies and fragments, which retain their immunoreactivity.
A two-year study of the long-term stability of carrier-free polonium solutions under various acidity conditions over periods of up to 9 years was reported on in 1993 by Colle [7].
AMSBIO's highly purified Chondroitinase ABC enzyme is supplied protease-free, carrier-free and with low-endotoxin levels for use in neuroscience and regenerative medicine research.
Animals in group I served as normal controls; group II animals were administered a dose of 3.7 Mbq of 131I (carrier-free) intraperitoneally, group III animals were supplemented with zinc (227 mg/l drinking water) and animals in group IV were given a combined treatment of zinc as well as 131I.
The treatment combinations were: (1) no fertiliser applied and carrier-free [sup.32]P placed in the 40-mm band position; (2) no fertiliser applied and carrier-free [sup.32]P placed in the 80-mm band position; (3) 25 kg P/ha mixed with [sup.32]P and placed in the 40-mm band position; (4) 25 kg P/ha applied in the 40-mm band position and carrier-free [sup.32]P placed in the 80-mm band position; (5) 25 kg P/ ha mixed with [sup.32]P and placed in the 80-mm band position.
Constraints on the stability of molecules radiolabeled with carrier-free "I atoms dictate the minimum usable amount of labeled probe for adequate tracer detection in the assay (3).
If any cliche were to sum up UWB, it would be "What's old is new again." UWB has been around since the early 1 960s, known alternately as "carrier-free," "baseband" or "impulse" technology.
