Cell and tissue imaging
Imaging techniques can be used to look at organisms at a molecular, cellular or tissue level by the least invasive means possible.
Histology refers to the microscopic study of tissues and the cells that compose them. For this purpose, different marking techniques are used, such as coloring or the use of antibodies. Histology is a technique widely used in the diagnosis of abnormal cells and in the study of the distribution of markers in cells.
Microscopy is a set of imaging techniques on a microscopic scale. Different techniques can be used such as confocal microscopy (fluorescence microscopy) or transmission electron microscopy (electron beam).
Cytometry is a technique used to study suspended particles in a sample. These particles pass through a laser beam, allowing them to be characterized and counted. Cytometry is used in immunology because it is very suitable for marking many markers simultaneously. Cell sorting is an adaptation of flow cytometry, making it possible for cells to be recovered according to criteria defined in advance.
