The design of such probes is relatively new. Eukaryotic cells contain subcellular structures responsible for carrying out essential functions for cell survival, including generating energy PKH26 is a redfluorescent dye. We synthesized molecules related to 9-(dicyanovinyl)-julolidine (DCVJ), which featured hydrocarbon chains of different length to increase membrane compatibility. The method of FRAP is based on directing a focused laser beam at the cell membrane, which destroys the fluorescent dye in a defined region. 206700. Many of the mitochondria dyes are dependent on mitochondrial membrane potential and can therefore be used to monitor membrane potential changes that occur during processes such as apoptosis. DiA and DiI (60010) have been These dyes are Fluorescein diacetate freely penetrates intact cells where it is hydrolyzed to its fluorochrome, fluorescein, which is retained in the cell due to its polarity. 5702. Description. The DNA is stained with DNA dyes, and the dyes are combined with the DNA chains in a certain way. University of Virginia. They come in 3 colors, living cells should 1) enable adequate staining (which should not fade too quickly), 2) not impair the viability of the labeled cells, and 3) not interfere with the function to be tested (e.g., membrane fusion or phagocytosis). IVISense DiR 750 is a lipophilic, near infrared (NIR) fluorescent cyanine dye ideal for staining cytoplasmic membrane. The ideal fluorochrome for staining living cells should 1) enable adequate staining (which should not However, aggregation is a very common phenomenon of dyes .
