AIM: To study the distribution of protein kinase C (PKC) in living smooth muscle cells using fluorescent PKC probe. METHODS: Cell imaging analysis staining with fluorescent PKC probe, fim-1 diascetate. RESULTS: The PKC label intensity was largely diffused in the cytosol AIM: To study the distribution of protein kinase C (PKC) in living smooth muscle cells using fluorescent PKC probe.
