AngioSense 680, AngioSense-IVM 680
AngioSense 750, AngioSense-IVM 750

These fluorescence agents are large (250k MW) macromolecules that remain localized in the vasculature for extended periods of time (approximate half life in plasma 6 h) to facilitate imaging and to monitor angiogenesis. IVM formulations are optimized for intravital microscopy.

Image: In vivo confocal data images acquired using the same parameters: 637nm Laser Projections with a 10 μm step size (20 serial images).
Investigation: Arthritis was induced using an anti-collagen antibody cocktail followed 3 days later by LPS in Balb/c mice. Angiosense was injected on day 6 (early disease) and imaged on the IVM 20-25 min later.
