KAPA SYBR Fast One-Step qRT-PCR Kits

For Research Use Only. Not for use in diagnostic procedures.
KAPA qPCR

Overview

KAPA SYBR FAST One-Step qRT-PCR Kits are designed for optimal performance in stringent qRT-PCR reaction conditions, exhibiting improvements in sensitivity, specificity, reaction efficiency, and fluorescence. The kits contain an M-MuLV reverse transcriptase, an RNase inhibitor, and a novel DNA polymerase engineered through our directed evolution technology.

Benefits of KAPA SYBR FAST One-Step qRT-PCR Kits

  • Rapid one-step, one-tube RNA quantification, reducing experimental variation and contamination
  • A convenient qRT-PCR protocol
