Traditional animal models to quantify the degree of blood vessel formation are being replaced by cell culture assays
that are easier to set up, statistically reliable and can be automated in a drug screening laboratory. These assays rely on the endothelial cells’ ability to form distinct blood-vessel-like tubules in an extracellular matrix where they can subsequently be visualized by fluorescence microscopy. - [Read An Image-Based Assay of Endothelial Cell Tube Formation as a Model of Angiogenesis]
Cell Staining for Immunofluorescence Microscopy. Includes protocols for fixing the cells, Coverslip Preparation for Adherent Cells, Coverslip Preparation for Non-Adherent Cells, Paraformaldehyde Fixation, and Methanol/Acetone Fixation. Blocking protocols include blocking with primary antibody, and incubation with secondary antibody. - [Read Cell Staining for Immunofluorescence Microscopy]
Manual measurement and manipulation of the cell surface requires access to the cells, usually in an open chamber. Temperature-controlled chambers or stage inserts are preferred for maintaining physiological activity during the experiment. For example, heated culture dishes with coverslip glass bottoms (Bioptechs) permit high-resolution fluorescence microscopy of living cells during force application. - [Read Chambers for Examination of Live Cells under Mechanical Stress Protocol]

When imaging specimens in the optical microscope, differences in intensity and/or color create image contrast, which allows individual features and details of the specimen to become visible. Contrast is defined as the difference in light intensity between the image and the adjacent background relative to the overall background intensity. In general, a minimum contrast value of 0.02 (2 percent) is needed by the human eye to distinguish differences between the image and its background. - [Read Contrast in Optical Microscopy]

The visibility of the faint star light is enormously enhanced against a dark background. This principle is applied in darkfield (also called darkground) microscopy, a simple and popular method for making unstained transparent specimens clearly visible. Such objects often have refractive indices very close in value to that of their surroundings and are difficult to image in conventional brightfield microscopy. - [Read Darkfield Illumination]
Certain fluorescent dyes such as Blankophor have a high affinity for the b -glycosidically linked polysaccharides such as glucan and chitin, which are main the constituents of the fungal cell wall. Therefore, these fluorescent dyes can be used for screening clinical samples for the presence of fungal elements. This procedure can be performed using the following specimens: Nail, Skin, Bronchial alveolar lavage fluid, Sputum and Biopsies. - [Read Detection of Fungi by Fluorescence Microscopy Using Fluorescent Brighteners]
Protocol describes here a high sensitivity indirect detection procedure for DIG-labeled hybridization probes. The procedure uses the components of the HNPP Fluorescent Detection Set to form a fluorescent precipitate of HNPP (2-hydroxy-3-naphthoic acid-2’-phenylanilide phosphate) and Fast Red TR at the site of hybridization. Includes: In situ hybridization with DIG-labeled probes; Detection of DIG-labeled probes; Fluorescence microscopy. - [Read DNA In Situ Hybridization with an Alkaline Phosphatase-Based Fluorescent Detection System]

Article describe the preparation of cells for correlative electron microscopy after live light microscopic observation of fluorescently labeled cytoskeletal proteins microinjected into the same cells. Since identification of cytoskeletal elements in electron microscopic preparations is an essential part of any correlative study, procedures for immunogold labeling of cytoskeletal components and for myosin S1 decoration of actin filaments are also described. - [Read Electron Microscopy of the Cytoskeleton of Cultured Cells]
