This field utilises specific reagents to illuminate biological processes, allowing scientists to observe and measure diverse cellular activities in real-time. These innovations are indispensable tools in drug discovery, gene expression analysis, and disease model studies, providing unprecedented insights into complex biological systems.

Bioluminescent imaging relies on the emission of light by living organisms. Key reagents like luciferin potassium salt and caged luciferin probes play crucial roles in this technology. For instance, luciferin potassium salt, when introduced into a living system, emits light in the presence of luciferase, enabling the tracking of dynamic processes such as tumour progression and metastasis. This visibility is invaluable for researchers monitoring cancer therapies in animal models, giving them a real-time window into the effectiveness of treatments.

Additionally, caged luciferin probes offer a sophisticated mechanism to study cellular events with high precision. These probes release luciferin in response to specific cellular conditions, allowing for precise temporal and spatial control. This high-target specificity is especially useful in uncovering the roles of various genes and proteins in complex biological pathways. For example, researchers have utilised these probes to investigate the circadian rhythms in animal models, leading to breakthroughs in understanding sleep disorders.

Fluorescent imaging, on the other hand, involves substances like ICG NHS ester. This reagent is a fluorescent dye that binds covalently to proteins, making it an excellent tool for visualising protein interactions and localisation within cells. When used in animal model research, ICG NHS ester can highlight angiogenesis (formation of new blood vessels) in tumours, providing critical data for oncology studies. However, its tendency to photobleach (lose fluorescence over time) can limit long-term studies, prompting ongoing efforts to enhance dye stability.

Another cornerstone of functional imaging is the development and use of bioluminescent cell lines. These cell lines are genetically engineered to express luciferase, providing a stable light source for tracking cellular processes in vivo.
