Figure 1. Staining effect of Tubulin Tracker Red on NRK-52E cells (rat renal tubular epithelial cells). Figure A shows the morphology of rat renal tubular epithelial cells under bright field conditions; The green fluorescence represents microfilaments stained with Actin Tracker Green-488 (Figure B), the red fluorescence represents microtubules stained with Tubulin Tracker Red (Figure C), and Figure D shows the overlay of triple staining of Tubulin Tracker Red, Actin Tracker Green-488, and Hoechst 33342. The measured data may vary due to differences in experimental conditions, testing instruments, etc. The data in the figure is for reference only.
