Unique silica gel membranes selectively and efficiently adsorb large fragment of genomic DNA.

Selective filtration of small fragments of DNA or RNA, while also greatly reducing salt and protein carryover on the membrane.

binding capacity: up to 25 μg of 200 bp~50 kb DNA fragment.

Extremely stable DNA adsorption performance, no degradation of performance after two years at room temperature (0~30°C).
