SYBR Green I chloride is a highly sensitive fluorescent nucleic acid dye that binds specifically to the minor groove of double-stranded DNA or intercalates between base pairs. SYBR Green I chloride exhibits weak fluorescence in the unbound state but emits bright fluorescence upon binding, and it preferentially binds to large-fragment DNA and DNA with high G+C content. SYBR Green I chloride is suitable for real-time PCR technology; its fluorescence intensity correlates with the amount and size of amplification products, enabling accurate quantification of gene expression and discrimination of amplicons via melting curve analysis without additional post-processing. SYBR Green I chloride is widely used in preclinical in vitro nucleic acid detection .
