sybr green ii

1) Non-toxicity: belong to flower-stem dye, easy to biodegrade, no carcinogenic toxicity. 2) High sensitivity: at least 100pg ssDNA or RNA can be detected, which is 25 ~ 100 times higher than EB staining. 3) High SIGNal-to-noise ratio: the sample fluorescence signal is strong, while the background signal is low. 4) Simple operation: like EB, the dye does not degrade in the prefabricated gel and electrophoresis process;The dyeing process after electrophoresis takes only 30 minutes without decoloring or washing, and can be observed directly with ultraviolet gel transmission or visible light transmission.

SYBR Green I is an asymmetrical cyanine dye, which is used to detect nucleic acids. It consists of a N-alkylated benzothiazolium or benzoxazolium ring system, that is joined by a monomethine bridge to a pyridinium or quinolinium ring system. SYBR Green I binds to the minor groove of dsDNA and is excited at a wavelength of 480 nm. It has a peak fluorescence emission of 520 nm.
