Fluoroshield with PI is an aqueous mounting medium for preserving fluorescence of tissue and cell smears. This mounting medium is fortified with propidium iodide (PI) which is a counterstain for DNA. For use in in situ hybridization techniques or other methods where fluorescence of DNA staining is required. PI excites at 535 nm and emits at 615 nm, producing a red fluorescence. RNA is also stained with PI.
