Getting Sharper 3D Images of Thick Biological Specimens with Widefield Microscopy
Widefield fluorescence microscopy is often used to visualize structures in life science specimens and obtain useful information. With the use of fluorescent proteins or dyes, discrete specimen…Read articleDrosophila Testis Niche Stem Cells – Three Color Computational Clearing
Differentiated living beings such as humans, but also a fruit fly or a plant, possess not only the differentiated cells which form specific tissues, but also those cells whose fate is not yet (or only…Read articleWhere to go? Cellular Migration requires coordinated Transitions of Actin Cortex
Plants, Bacteria, and Fungi possess a rigid cell wall that protects the cell and gives it shape. Animal cells, such as mammalian cells, have no outer wall, which exposes their plasma membrane to the…Read articleAlzheimer Plaques: fast Visualization in Thick Sections
More than 60% of all diagnosed cases of dementia are attributed to Alzheimer’s disease. Typical of this disease are histological alterations in the brain tissue. So far, there is no cure for this…Read articleVisualize developmental patterns in Drosophila
The marvelous complexity of life is perhaps the greatest source of fascination within the biological sciences. Among the most complex subjects within biology is the development of multicellular life.…Read articleZebrafish Brain - Whole Organ Imaging at High Resolution
Structural information is key when one seeks to understand complex biological systems, and one of the most complex biological structures is the vertebrate central nervous system. To image a complete…Read articleWhat is a Spectral Detector (SP Detector)?
The SP detector from Leica Microsystems denotes a compound detection unit for point scanning microscopes, in particular confocal microscopes. The SP detector splits light into up to 5 spectral bands.…Read articleWhat is a Resonant Scanner?
A resonant scanner is a type of galvanometric mirror scanner that allows fast image acquisition with single-point scanning microscopes (true confocal and multiphoton laser scanning). High acquisition…Read articleWhat is a Field-of-View Scanner?
A field-of-view scanner is an assembly of galvanometric scanning mirrors used in single-point confocal microscopes that offer the correct optical recording of large field sizes. The field-of-view…Read articleResolved Field Number (RFN)
The field number (FN) for optical microscopes indicates the field of view (FOV). It corresponds to the area in the intermediate image that is observable through the eyepieces. Although, we cannot…Read articleWhat is a Tandem Scanner?
A Tandem Scanner is an assembly of two different types of scanning together in one system for true confocal point scanning. The Tandem Scanner consists of a three-mirror scanning base with the…Read articleWhich Sensor is the Best for Confocal Imaging?
