Sybr green structure

WebThe single stranded DNA (ssDNA) with G-rich sequence can fold into G-quadruplex via intramolecular hydrogen-bonding interaction in the presence of ligand. This structure conversion can be specifically detected by a fluorescence method based on different interaction between SYBR Green I (SG) and various DNA structures. WebApplied Biosystems SYBR Green master mixes are designed for quantitative real-time PCR using a set of two PCR primers that flank the target region. The master mixes contain buffer, dNTPs, thermostable hot-start DNA polymerase, and SYBR Green dye—everything needed for real-time PCR. Find the best master mix by application.
