SsoAdvanced™ SYBR® Green Supermix Sso7d Polymerase

■■ Robust formulation delivers performance across a broad range of standard
and fast cycling conditions www.bio-rad.com/
supermixes
■■ Sso7d fusion polymerase and optimized buffer deliver fast reaction times via
instant polymerase activation and rapid polymerization kinetics to generate
exceptional qPCR results in less than 30 min
■■ Increased resistance to PCR inhibitors ensures maximum efficiency,
sensitivity, and reproducibility, and allows increased fluorescence
when compared to other SYBR® Green supermixes
■■ Advanced formulation tolerates a broad range of reaction conditions,
primer concentrations, and temperature ranges The dsDNA binding protein, Sso7d, stabilizes the polymerase-template complex,
increases processivity, and provides greater speed and reduced reaction times compared
to conventional DNA polymerases. Sso7d fusion polymerases are significantly more resistant to
PCR inhibitors, making the SsoAdvanced and SsoFast supermixes ideal choices for challenging
applications, such as direct qPCR, without the need for sample preparation.
