Labels can be applied in histology using various techniques:
1. Manual Annotation: Involves manually marking the slide using a microscope or digital tools. 2. Digital Labeling: Utilizes software to annotate digital images of slides. This can include the use of colors, arrows, and text. 3. Immunohistochemistry (IHC): Uses antibodies tagged with markers (such as fluorescent dyes) to label specific proteins or antigens in tissues.
