Biological irradiators are specialized devices that deliver controlled doses of ionizing radiation to biological samples, such as cells, tissues, and small organisms. These tools are invaluable in cell and molecular biology research for a variety of applications. 1. Cell Cycle and Apoptosis Research Cell Cycle Arrest: Ionizing radiation can induce cell cycle arrest at specific checkpoints, allowing researchers to study the regulation of the cell cycle and the role of various proteins in cell cycle control. Apoptosis Induction: Radiation can trigger programmed cell death (apoptosis), providing a model to study the molecular pathways involved in apoptosis and the role of different genes and proteins in this process.

great, i mean GREAT animations!

Great, thoroughly explained 3D cellular processes and molecular processes animations.

A collection of interactive simulations and learning activities produced using the Molecular Workbench are provided at this site. All exhibits are results of calculations based on scientific principles.

Molecular models for you to play with. You can move, rotate and resize them, change them from space-filling models into wire-frame models and back again, or simply sit back and admire the animation!

Optical molecular imaging is a powerful tool in drug development, offering unique capabilities for visualizing and quantifying biological processes at the molecular and cellular levels. This non-invasive imaging technique uses light to detect and measure the presence of specific molecules, cells, or biological events in living organisms. 1. Target Identification and Validation Biomarker Discovery: Optical imaging can be used to identify and validate biomarkers that are indicative of disease states or therapeutic responses. Fluorescent and bioluminescent probes can highlight specific molecular targets, helping researchers understand their role in disease progression.

Preclinical imaging and biological irradiation are pivotal in the development of new animal models, significantly enhancing the precision and depth of research. 1. Preclinical Imaging Preclinical in vivo imaging techniques allow researchers to non-invasively visualize and monitor disease progression, anatomical changes, and molecular processes in real-time, providing critical insights into the pathophysiology of various conditions. This capability enables the creation of more accurate and representative animal models of human diseases, such as cancer, neurological disorders, and cardiovascular diseases.

Micro-CT and optical molecular imaging are powerful tools in cardiovascular research, each offering unique capabilities that enhance our understanding of cardiovascular diseases, development, and treatment. Here are some key applications of these imaging modalities in cardiovascular research: 1. Micro-CT Imaging Vascular Morphology and Anatomy 3D Visualization: Micro-CT provides high-resolution, three-dimensional images of the vascular system, allowing detailed visualization of blood vessels, including small capillaries and complex vascular networks.
