High-efficiency extraction of microbial & environmental DNA from complex soil matrices
The GSure® Soil DNA Isolation Kit is a robust, inhibitor-removal–optimized system designed to extract high-quality DNA from all types of soil, sludge, sediment, compost, and environmental particulate samples. Soil is among the most challenging sample types due to humic substances, polyphenols, heavy metals, and organic inhibitors. The GSure® kit combines mechanical disruption, chemical lysis, and multi-step inhibitor elimination to deliver PCR-ready, inhibitor-free DNA ideal for molecular biology and metagenomic applications.
This kit is suitable for research laboratories, agricultural biotechnology, environmental monitoring, microbial ecology, biodiversity studies, and industrial soil analysis workflows.
● Superior Inhibitor Removal System: Multi-stage extraction with GSD4 and GSD5 buffers efficiently eliminates humic acids, polyphenols, and other PCR inhibitors—common problems in soil DNA isolation.
● High Yield & High Purity DNA: Optimized lysis with GSD1–GSD3 buffers ensures strong recovery of bacterial, fungal, viral, and microbial community DNA from even the most challenging soil types.
● Silica Column–Based Purification: GMini Spin Columns allow fast, consistent, and high-quality DNA purification.
● Suitable for All Downstream Applications: Purified DNA performs reliably in PCR, qPCR, metagenomics, NGS, DGGE, cloning, sequencing, and community profiling.
● Fast, Streamlined Workflow: Complete DNA isolation in ~40 minutes using standard centrifuge equipment.
● Industry-Grade Performance at an Economical Cost: Comparable output to leading global kits (e.g., Qiagen, Macherey-Nagel) at significantly lower cost.
● Stable Storage Conditions: Buffers GSD3 and GSD4 stored at 4°C; all other components stored at room temperature for easy handling.
