Dapi staining troubleshooting
WebDAPI Staining Solution (ab228549) is a fluorescent stain for labeling DNA in fluorescence microscopy. Since DAPI passes through an intact cell membrane, it can be used to stain live cells and fixed cells. Molecular Weight: 350.25 Notes DAPI’s absorption maximum when bound to double-stranded DNA is at 358 nm and its emission maximum is at 461 nm. WebStaining solution: 0.1% PBT + 1:1000 Phalloidin + 1:2000 DAPI (or stains of choice at correct concentrations) Steps 1. Remove media from the 384-well plate using a multichannel aspirator connected to a vacuum.
