YO-PRO-1
Based on 1 Customer Validation
YO-PRO-1 is a non-cell-membrane-penetrating green fluorescent dye. YO-PRO-1 cannot penetrate normal cell membranes but can penetrate the membranes of apoptotic and necrotic cells. YO-PRO-1 has a high affinity for DNA. When it is not bound to DNA, it emits almost no fluorescence, and when it binds to DNA, it can emit green fluorescence (Ex/Em: 488/530±30 nM). YO-PRO-1 is often used together with Propidium Iodide (HY-D0815) to analyze and identify apoptotic and necrotic cells.

Biological Activity
Simple steps for YO-PRO-1 staining: Prepare cell/tissue samples; Wash the samples after incubating with YO-PRO-1 for 30 minutes to 1 hour. It can be co-stained with Hoechst 33342 (HY-15559), Propidium Iodide (HY-D0815), etc.; Microscopic observation and detection: Image by excitation with a 488 nm laser line[1][2].
