Radiolabelled human immunoglobulins have been available for 5 years. Within that time there have been many publications on the use of these agents labelled with both technetium-99m (99Tcm) and indium-111 (111In). The results of these data appear contradictory and only now do we understand both some of the mechanisms of radiolabelled immunoglobulins and some of their limitations. While 111In-polyclonal immunoglobulin seems to have a wide range of clinical applications in infection and inflammation, the more readily available 99Tcm-labelled product is best suited to the localization of peripheral bone and joint disease. The ease of producing these agents from commercially available immunoglobulins will ensure continued interest and research into these new tracers.

Labeling DNA Probes03:31

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...

Immunogold Electron Microscopy

Immunoelectron microscopy utilizes immunogold labeling of endogenous proteins with specific antibodies to detect and localize these proteins in cells and tissues. The procedure provides insights into the distribution and quantification of protein under different stimulation conditions offering clues about their functions. Conjugating highly electron-dense gold particles with primary or secondary antibodies allow antigen detection on and within cells, with high resolution and specificity.
