Zellpräparation

Zellpräparation refers to the methods and techniques used to prepare cells for microscopic examination or other analytical procedures. The primary goal of Zellpräparation is to preserve the cellular structure and morphology, making them visible and interpretable under a microscope or suitable analytical instrument. This process is crucial in various fields, including biology, medicine, and research, as it allows for the study of cellular components, disease diagnosis, and drug development.

Several common methods are employed in Zellpräparation. One of the simplest is smear preparation, where cells are spread onto a slide, often with the aid of a fixative. Another technique is cell suspension, where cells are dispersed in a liquid medium. For more detailed structural analysis, tissue samples may be embedded in a supporting medium such as paraffin or frozen, then sectioned into thin slices. Fixation is a critical step that stabilizes cellular components and prevents degradation. Common fixatives include formaldehyde and ethanol. Staining is often employed after fixation to enhance the contrast of cellular structures, making them more readily visible. Various stains are available, each targeting specific cellular components like nuclei or cytoplasm. The choice of Zellpräparation method depends on the type of cell or tissue, the intended analysis, and the required level of detail.
