AO/PI Double Staining Kit
AO/PI Double Staining Kit is a kit that can rapidly detect cell viability. This kit provides two dyes, Acridine Orange (AO) and propidium iodide (PI). AO can penetrate cell membranes, staining normal cells in green. Chromatin condensation is a hallmark of apoptosis. AO can stain condensed chromatin of apoptotic cells more brightly than normal cells. PI cannot penetrate the cell membrane and cannot stain normal cells or apoptotic cells red; for necrotic cells (whose membrane loses integrity), PI can stain them red. The staining pattern using these two dyes makes it possible to distinguish normal, apoptotic and necrotic cells.

| Components | K2238-100 T | K2238-500 T |
| AO staining solution | 500 μL | 5 x 500 μL |
| PI staining solution | 500 μL | 5 x 500 μL |
