Description

PerfeCTa® SYBR® Green FastMix, Low ROX™ is a 2X concentrated, ready-to-use reaction cocktail that contains all components, except primers and template for real-time quantitative PCR on Applied Biosystems 7500 or Stratagene MX series of real-time PCR systems. This unique combination of proprietary buffer, stabilizers, and AccuFast™ Taq DNA polymerase deliver maximum PCR efficiency, sensitivity, specificity and robust fluorescent signal using fast, or conventional, cycling protocols with SYBR® Green qPCR. Highly specific amplification is crucial to successful qPCR with SYBR® Green I dye technology because this dye binds to and detects any dsDNA generated during amplification. AccuFast Taq DNA polymerase is a key component of this reaction mix. This hot-start Taq contains a proprietary mixture of monoclonal antibodies that bind to the polymerase and keep it inactive prior to the initial PCR denaturation step (> 48 hours at room temperature). Similar to our AccuStart Taq DNA polymerase, these antibodies are irreversibly inactivated during the initial PCR denaturation step. However, unlike other antibody hot-start polymerases, activation of AccuFast Taq is instantaneous at 95°C. Rapid recovery of fully active, unmodified Taq DNA polymerase is critical for efficient extension kinetics. Replication of fragments up to 200 bp is complete in less than 20s at 60°C.

Storage conditions

PerfeCTa® SYBR Green FastMix, Low ROX is stable for 1 year when stored in a constant temperature freezer at -20°C, protected from light. For convenience, it may be stored unfrozen at +2 to +8°C for up to 6 months. After thawing, mix thoroughly before using. Repeated freezing and thawing of the product is not recommended. However, the product demonstrated no loss of performance after 20 freeze-thaw cycles or 2 months at +20°C.
