Several alternatives exist for detecting cell proliferation, including: - EdU Labelling: Similar to BrdU but uses a click chemistry reaction for detection, offering a simpler and faster protocol. - Ki-67 Staining: Targets the Ki-67 protein, which is present during active phases of the cell cycle but absent in resting cells. - PCNA Staining: Detects the Proliferating Cell Nuclear Antigen, a marker for cells in the DNA synthesis phase.
