In histology, TERT is studied using various staining and imaging techniques. One common method is immunohistochemistry (IHC), which involves the use of antibodies specific to TERT to detect its presence in tissue samples. This technique allows researchers to visualize the localization and quantify the expression of TERT in different cell types. Another method is in situ hybridization (ISH), which can be used to detect TERT mRNA within tissue sections.
