In Histology, the effects of RNAi can be visualized using various techniques: - In Situ Hybridization: This method allows for the detection of specific RNA molecules within tissue sections, providing insights into the localization and expression patterns of the target mRNA. - Immunohistochemistry: By using antibodies against the protein products of the target genes, researchers can observe the reduction in protein levels as a result of RNAi. - Fluorescence Microscopy: Tagged siRNA or miRNA can be visualized within cells and tissues to study the uptake and distribution of RNAi molecules.
