Vascupaint™ Yellow is a high-performance, lead-free silicone injection compound specifically optimized for micro-CT imaging of microvascular structures. This yellow-pigmented formula provides exceptional X-ray attenuation, allowing for high-contrast 3D visualization of vascular networks following alcohol-based tissue clearing or within opaque samples. As a low-viscosity alternative to traditional lead-based media, Vascupaint™ Yellow ensures effortless and complete perfusion of non-surviving organisms and human organs for precise ex vivo vascular cast analysis. While the Vascupaint™ line includes green, blue, and clear options for fluorescence or custom preparations, the Yellow formulation is the primary choice for researchers requiring maximum fidelity and structural detail in computed tomography.
