Product description

Hifair™ Advanced One Step RT-qPCR SYBR Green Kit is a kit for fluorescence quantification based on SYBR Green I dye. Using gene-specific primers, reverse transcription and qPCR reactions are completed in one tube, eliminating the need for repeated cap-opening and pipetting operations, greatly improving assay efficiency and reducing the risk of contamination. For RNA samples, the kit employs heat-resistant Hifair™ V Reverse Transcriptase for efficient cDNA synthesis and UNICON™ HotStart Taq DNA Polymerase for quantitative amplification. Under the optimized buffer system, the sensitivity of the kit can be as high as 0.1 pg for highly expressed targets and as high as 1 pg for moderately expressed targets, and the kit is also suitable for amplification and quantification of DNA samples. The kit is suitable for the amplification and quantification of DNA samples. It enables the sensitive detection and quantification of nucleic acids from different plant and animal samples, cells and microorganisms.

** The final primer concentration was 0.2 μmol/L, which could also be adjusted between 0.1 and 1 μmol/L as appropriate.

*** The reagent is extremely sensitive, with Total RNA in the range of 1 pg-1 μg, and testing of human samples showed an optimal input of 1 pg-100 ng, controlling for an overall Ct value in the range of 15-30 as appropriate.

**** It is recommended to use 20 μL or 50 μL to ensure the validity and reproducibility of target gene amplification.

***** Please prepare in the ultra-clean bench and use nuclease residue-free tips and reaction tubes; tips with filter cartridges are recommended. Avoid cross contamination and aerosol contamination.
