Sự miêu tả
This kit integrates a visible-light LAMP indicator into the formulation. The reaction buffer contains dATP, dCTP, dGTP, and dUTP—together with additional components essential for Bst II DNA Polymerase amplification—as well as a pH-sensitive indicator. The kit also provides glycerol-free Bst II DNA Polymerase, UDGase, and reverse transcriptase (RT enzyme), and is supplied with a lyophilization protectant, enabling direct preparation of lyophilized reaction systems on a standard freeze-dryer. The reagent delivers high amplification efficiency and sensitivity, with amplification results readable by the unaided eye: positive reactions turn orange-yellow while negative reactions remain magenta, providing strong visual contrast.

Applications
Features
• One-step isothermal RNA amplification: visual colorimetric readout eliminates the need for electrophoresis or fluorescence instrumentation.
• Rapid turnaround: pathogen status can be determined in as little as 30 minutes after sample loading.
• Flexible workflow: a constant-temperature water bath or standard PCR thermal cycler (60–65°C) is sufficient—no specialized LAMP instrument required.
• Lyophilization-ready: glycerol-free enzymes and a dedicated lyophilization protectant enable direct preparation of room-temperature-stable lyophilized kits.
• High contrast endpoint: orange-yellow (positive) versus magenta (negative) for unambiguous visual interpretation, suitable for high-throughput population screening.
Storage
Part I — Components 13920-A and 13920-D [2.5× pH-Sensitive Reaction Buffer / Lyophilization Protectant] are shipped on dry ice and should be stored at -25 to -15°C with a shelf life of 6 months.
Part II — Components 13920-B and 13920-C [Glycerol-free RT Enzyme Mix / Bst Enzyme] are shipped with ice packs and should be stored at 2 to 8°C with a shelf life of 3 months.
FAQ
Q: Can 13920ES be used directly without lyophilization?
Yes. Lyophilization is optional; the kit may be used directly as a liquid formulation without any loss of performance.
Q: The 13920ES protocol includes an 85°C inactivation step for 5 minutes. Should the tube be removed after this inactivation step, or after the 30-minute reaction at 60–65°C, for color observation?
A: The tube should be removed for color observation only after the 85°C inactivation step (5 minutes) has been completed.
