asp 4

4-Di-1-ASP is a positively charged fluorescent dye used to label glioma cells in live brain tissue and can also be used to observe mitochondria in live cells, with λex λem = 475 606 nm.

4-Di-16-ASP, a green fluorescent membrane dye, exhibits lipophilic properties and functions as an aminostyryl probe with a broad emission spectrum, detectable through green, orange, or red filters. This compound is frequently utilized in neuronal membrane tracing, offering quicker diffusion compared to DiO [1].

4-Di-10-ASP, a fluorescent lipophilic tracer (Excitation 485 nm; Emission 620 nm), specifically stains phospholipid membranes [1] [2].

4-Di-2-ASP, a styryl pyridinium fluorescent dye, serves as an essential mitochondrial marker. It effectively and specifically labels pulmonary NEBs (neuroepithelial bodies) [1].
