Description
Chai Green™ is a new DNA binding dye optimized for Real-Time PCR and High Resolution Melt (HRM) analysis. It is significantly less inhibitory than SYBR Green because it binds primarily within the minor groove of DNA. Because of its lower inhibition, it may be used in higher concentrations resulting in increased fluorescence output, making it ideal for sensitive applications like HRM. The decreased PCR inhibition also decreases detection times in isothermal amplification applications.
Chai Green is compatible with all Real-Time PCR instruments supporting SYBR or FAM fluorophores, as its fluorescence spectrum is similar to SYBR Green. Dye binding appears to be cooperative and is influenced by the dye concentration and dye-to-basepair ratio.
Chai Green Fluorescence Spectrum
The fluorescence spectrum of Chai Green™ is similar to that of SYBR Green.
