This video demonstrates an in vivo immunofluorescence localization (IVIL) technique to study the biodistribution of tumor-targeting antibodies in a murine model of breast cancer. Upon the intravenous injection of a tumor-specific antibody in the mouse, the tumor is surgically isolated, and the localization of the antibody within the tumor tissue is confirmed via ex vivo immunostaining.

Source: Peiman Shahbeigi-Roodposhti and Sina Shahbazmohamadi, Biomedical Engineering Department, University of Connecticut, Storrs, Connecticut Nanoparticles have been increasingly used research towards targeted drug delivery and controlled drug release. While most of these particles have been developed as polymeric or liposomal particles because of their biocompatibility, there is a trend in current research toward the use of metallic and magnetic nanoparticles. These metallic nanoparticles...

This work describes methods to establish acute and chronic hyperglycemia models in zebrafish. The aim is to investigate the impact of hyperglycemia on physiological processes, such as constitutive and injury-induced neurogenesis. The work also highlights the use of zebrafish to follow radiolabeled molecules (here, [18F]-FDG) using PET/CT.

There are many research methods available to psychologists in their efforts to understand, describe, and explain behavior and the cognitive and biological processes that underlie it. In 2011, the New York Times published a feature story on Krista and Tatiana Hogan, Canadian twin girls. These particular twins are unique because Krista and Tatiana are conjoined twins, connected at the head. There is evidence that the two girls are connected in a part of the brain called the thalamus, which is a...
FAQs
Molecular structure and formulation influence how a compound behaves after administration, including where it reaches, how strongly it accumulates, and how efficiently it clears. Biodistribution studies therefore connect chemical design with absorption, distribution, metabolism, and excretion patterns. Comparing compounds or formulations can reveal why one design improves target-tissue exposure while another produces greater off-target distribution or dose-related risk.
The administered compound and the substances formed from it may have different tissue distributions and clearance patterns. Measuring both helps researchers determine whether observed exposure reflects the original molecule, its metabolites, or both. This distinction is chemically important because metabolism can change the distribution profile used to evaluate pharmacokinetic behavior, target exposure, and possible safety concerns.
Tissue accumulation shows whether exposure is concentrated at an intended target or extends into other organs and biological compartments. When results are examined across selected time points and doses, they can indicate persistence, clearance behavior, and dose-related changes. These patterns help connect chemical or formulation choices with potential off-target accumulation and support more informed safety assessment.
A typical workflow begins with administering a defined dose of the compound, drug, or biologic. Researchers then collect selected tissues or biological fluids at predetermined time points and quantify the substance or its metabolites. Analytical measurements are interpreted across sampled locations and times to determine distribution, accumulation, and clearance patterns within the organism.
Mass spectrometry can measure the administered substance or its metabolites in collected biological samples, while radiotracer detection provides a way to follow a labeled material through the organism. The overview identifies both as analytical approaches for biodistribution work. Selecting between them depends on the substance being evaluated and the type of distribution or clearance information required.
These studies are useful when researchers need to evaluate how chemical structure or formulation affects delivery and exposure. In drug development, they help identify target-tissue and off-target behavior. They also support nanomaterial evaluation and the design of delivery systems intended to improve where a compound travels, how long it remains present, or how effectively it reaches a relevant tissue.
