GSure DNA isolation kit delivers high amount of DNA from minimum amount of sample source. Purified DNA is free of protein and any sort of contamination. This kit provides a simple and convenient technique to isolate high-quality DNA from fresh or pre stored samples. GSure kit combines the advantages of a silica-based system with a microspin format. The buffers of each type of GSure DNA Isolation Kit are designed in such a way, they can deliver maximum yield from the corresponding sample types. Buffers of each individual isolation kit are such formulated that can isolate and purify genomic and plasmid DNA from wide variety of sample types, including tissue, cells, blood, serum, plants, fungi, algae, stool, urin, sputum and forensic samples. Sample preparation is the most crucial factor for better yield. Extracted DNA always maintains the absorbance ratio of 260nm/280nm between 1.78-1.82, explaining the quality of the isolated DNA.
