HelixAmpTM FastLAMP Kit is designed to provide a simple and faster solution for Loop-Mediated Isothermal Amplification (LAMP) of DNA targets. LAMP is an isothermal amplification technique that provides rapid detection of target nucleic acids. The 2x FastLAMP Buffer contains buffering reagents, dNTPs, Mg2+, salts, and proprietary enhancing agents. The FastLAMP Enzyme is a derivative of Bst DNA polymerase, large fragment.
HelixAmpTM FastLAMP Kit allows the fast amplification of target within 30 minutes with appropriate LAMP primer set.
Figure 1. Comparison of real-time fluorescence LAMP assays using HelixAmp™ FastLAMP kit and other competitors, derivatives of Bst DNA polymerase. The reaction mixtures contain a fluorescent intercalating dye for real-time monitoring of the DNA amplification and 1.0 fg of Lambda DNA (~20 copies) as template. HelixAmp™ FastLAMP kit shows the fastest amplification, and it reaches the plateau within 30 min reaction.
Figure 2. Sensitivity comparison of HelixAmp™ FastLAMP Kit and a competitor (Bst 3.0 polymerase). LAMP reactions were performed with purified genomic DNAs from N. meningitidis serogroup W (genome size = about 2,270 kb) as a template, ranging from 0.4 to 4 x 106 copies per reaction. After thirty minutes of reaction, the products were analyzed by an agarose gel electrophoresis. NTC, no template control.
Figure 3. Accuracy of the quantitative assay using HelixAmp™ FastLAMP kit. Serially diluted Lambda DNAs (2 x 106 ~ 2 x 101 copies) were analyzed using the Lambda specific LAMP primer set and an intercalating fluorescent dye. The accuracy of quantification is demonstrated by R² value= 0.998.
Figure 4. LAMP reactions of positive samples (serially diluted lambda DNAs, 2 x 106 ~ 2 x 101 copies) and no template control(NTC) using HelixAmp™ FastLAMP kit. The Tt (Threshold time) value of NTC reactions differs from that of positive reactions by about 20 minutes.
