Upright Intravital Spinning Disk Confocal

The VIVO SDC platform incorporates advanced optics, cameras, fast excitation sources, computers and proprietary electronics to achieve high speed, precision and flexibility in intravital image acquisition. The configuration of the VIVO system is designed to allow the presentation of surgically prepared animals and live tissue slices without compromising high-sensitivity imaging at fast speeds. Seamless integration of ablation lasers and photoactivation/photoconversion devices allows for complex photomanipulation experiments.

Highlights

Complete Cardiovascular Imaging Platform

VIVO SDC is designed around fast imaging of the mouse vasculature for thrombosis and inflammation studies. Over the past two decades, dozens of high-impact journal articles have been published with the VIVO SDC system focusing on platelet and leukocyte biology in numerous murine vascular beds including dermis/skin-flap, mesentery, cremaster, cerebral-microvessels (via cranial window) and for imaging of larger vessels including the femoral and carotid arteries. 3i applications scientists can offer training and guidance from experimental design to publication based on extensive personal experience in animal preparation, surgical techniques, intravital imaging and data analysis.

Intravital Thrombosis Imaging

The Ablate! laser system is used to trigger gentle and reproducible damage to the endothelial cells in live blood vessels to induce platelet adhesion and thrombus formation. Consistent pulses from the laser allow for tissue ablation before and after addition of an agonist or inhibitor for detailed kinetic studies of novel therapeutic targets. Power can be easily titrated from cell activation to multi-cell ablations with a diffraction-limited spot for precise targeting.

Platelet thrombosis formation is at the center of many cardiovascular diseases, including heart attacks, strokes and deep vein thrombosis (DVT). VIVO SDC equips researchers with a reproducible laser-induced thrombosis model in vivo by implementing a sensitive camera, fast LED brightfield & fluorescence illumination, Ablate! pulsed laser and easy-to-use SlideBook software. In this experiment the murine cremaster muscle is visualized in brightfield and platelets are fluorescently labeled in red. After the ablation event a thrombus forms and stabilizes inside of the arteriole. SlideBook offers advanced masking, segmentation and statistical analysis that makes quantifying thrombosis data easy.

Surgical Equipment & Training Resources

3i offers extensive equipment lists and recommendations for experimental setups. Training videos and journal articles offer researchers a quick starting point for performing advanced cardiovascular imaging experiments. Surgical trays for tissue presentation with custom inserts are available for multiple animal models.

Preclinical Research Pipeline

Intravital imaging has become essential in several fields including thrombosis & hemostasis, immunology, vascular biology, angiogenesis, biochemistry, gene therapy and cancer biology. Real-time imaging of cardiovascular events adds powerful in vivo results to studies of novel molecular mechanisms, accelerating drug discovery and decreasing the time to patient treatment. Intravital imaging with the VIVO SDC system is now being used to investigate and develop new therapies targeting hemophilia, leukemias and other cancers with circulating tumor cells, ischemic events, inflammation and other cardiovascular diseases.

Flexible and Robust Neuroscience System

Imaging the brain and nervous system of live organisms requires a gentle, fast and high-resolution system. VIVO SDC systems are used to image structure and calcium flux in live brain tissue slices as well as zebrafish and Drosophila brains. A large platform stage offers room for micromanipulators for neuronal patch clamp electrophysiology, paired with fluorescence imaging modalities through software triggering and synchronization capabilities. The addition of Phasor holographic photomanipulation enables rapid optogenetic stimulation while imaging.

Patch Clamp Electrophysiology

Patch clamp electrophysiology may be preferred for direct measurement of current and voltage changes taking place across the membrane in neural tissue. Several combinations of stages and micromanipulators can be paired with VIVO SDC systems including existing electrophysiology equipment.

Phasor Holographic Photomanipulation

Increasing Imaging Depth with VIVO Multiphoton

An intravital imaging system for brain slice and in vivo multiphoton imaging, VIVO Multiphoton Upright is available as an upgrade to the VIVO SDC system. A flexible and modular design allows for the integration of best-in-class components from platform stages to scanheads to 2P holographic photomanipulation. VIVO Multiphoton is optimized for imaging deeper into smaller model systems (Drosophila, C. elegans, zebrafish, brain slices and organoids) as well as rodent animal models.

CSU-W1 SoRa

CSU-W1 SoRa is an easy-to-use super-resolution microscopy solution utilizing a dual Nipkow disk assembly with microlenses on both the illuminating and pinhole disks. SoRa images have a 1.4x resolution improvement and deconvolved SoRa images have a 2x resolution improvement compared to standard spinning disk data. With a maximum speed of 200fps, low phototoxicity and no limitation on dyes or fluors, SoRa is ideal for super-resolution intravital imaging. SoRa is also available as an upgrade to existing CSU-W1 systems.
