Invicro’s ex vivo imaging team has expertise in histology, IHC, immunofluorescence, quantitative whole-body autoradiography (QWBA), microautoradiography (MARG) and receptor binding assays, among other techniques. Our histology facilities are fully-equipped with three cryostats, two whole-body cryomacrotomes for frozen sections, and four microtomes for cutting paraffin embedded tissue. Notably, we have developed a method termed Cryo-Fluorescence Tomography (CFT) that enables 3D visualization of fluorescent compound distribution in frozen tissue. We have expertise in IHC custom stain development, double or triple labeling on frozen and paraffin sections.
Our ex vivo imaging capabilities are often included at an endpoint in in vivo studies to provide high-resolution imaging, further expanding the value and information obtained per sample. This is achieved in a multi-modality approach in which the same pre-clinical sample is imaged whole using CFT and/or autoradiography to provide 3D high resolution information throughout the sample. Ex vivo 3D images are than co-registered with in vivo scans. Further tissue collection of sections from the same sample allows for microscopical examination thus providing cellular resolution. Our multi-modality approach together with our complementary ex vivo capabilities provide a unique opportunity to generate temporal and spatial information from low to high resolution in the same sample.
We have experience in many therapeutic areas including: oncology, neuroscience, bone, ocular, renal, inflammation, and cardiovascular. Invicro specializes in the development of novel image analysis methods, leveraging VivoQuant® and other internal tools for the quantification of image features from digitized slides.
