DNA Specific Fluorescent Probes
Features
DAPI binds to double-stranded DNA and emits blue fluorescence. It is known that fluorescence persistence is high and cell permeability is low compared to bisbenzimide (Hoechst).

|---|---|---|
| 045-30361 | 4',6-Diamidino-2-phenylindole Dihydrochloride n-Hydrate【DAPI】 | 358/461 |
Bisbenzimide H33258 Trihydrochloride (also known as Hoechst 33258) binds to the AT site of double-stranded DNA and emits blue fluorescence. And it shows membrane permeability.
| Product Number | Product Name | Ex/Em(nm) |
|---|---|---|
| 083-09971 | Bisbenzimide H33258 Trihydrochloride | 352/461 |
Bisbenzimide H33342 Trihydrochloride (also known as Hoechst 33342) binds to the AT site of double-stranded DNA and emits blue fluorescence. It has better membrane permeability than bisbenzimide H33258 trihydrochloride.
| Product Number | Product Name | Ex/Em(nm) |
|---|---|---|
| 080-09981 | Bisbenzimide H33342 Trihydrochloride | 350/461 |
