Chemical and biological properties of 2,6-diisopropyl IDA labelled with 99mTc
Abstract:
A procedure is described for the synthesis of 2,6-diisopropyl IDA (DISIDA) and for preparation of the radiopharmaceutical by "instant technique". The chemical parameters affecting the formation of the Sn(II)-DISIDA complex were also determined. Biological studies involved lyophylic measurements, determination of binding constants as well as rate of binding to proteins and biodistribution. Clinical investigation demonstrated good hepatobiliary features of this radiopharmaceutical.

Labeling DNA Probes
DNA probes are fragments of DNA labeled with a reporter tag to enable their detection or purification. The resulting labeled DNA probes can then hybridize to target nucleic acid sequences through complementary base-pairing, and may be used to recover or identify these regions.
Radioisotopes, fluorophores, or small molecule binding partners like biotin or digoxigenin, are the most widely used reporter tags for labeling DNA probes. These labels can be attached to the probe DNA molecule via...

Imaging Studies II: Positron Emission Tomography and Scintigraphy
Positron Emission Tomography (PET) is a medical imaging technique that provides crucial insights into the body's physiological functions at a molecular level. It is an indispensable resource for diagnosing, staging, and monitoring various illnesses, notably cancer, neurological disorders, and cardiovascular conditions.
