SYBR Green I (SG) is an asymmetrical cyanine dye used as a nucleic acid stain in molecular biology. SYBR Green I binds to double-stranded DNA. The resulting DNA-dye-complex absorbs blue light (λ_max = 488 nm) and emits green light (λ_max = 522 nm). SYBR Green I could replace the very strong mutagen ethidium bromide.

Similar cyanine dyes:

• SYBR Green II
• SYBR Gold
• YO (Oxazole Yellow)
• TO (Thiazole Orange)
• PG (PicoGreen)
