From sample collection, preservation, and DNA isolation to sequencing and analysis services from our highly skilled technicians, let Norgen Biotek be the one-stop shop for your microbiome needs. The microbial composition of a sample can begin to change at the point of collection. Freezing is often considered the gold standard—however, this is not always an option when collections are done off-site. Use of a chemical preservation system is becoming widely accepted by researchers trying to circumvent data analysis bias. Such a system also ensures that all types of DNA (bacterial, fungal, viral, host, etc.) will be bound during isolation. Common methods for stool DNA isolation include magnetic bead–based, column-based, 96-well, and automated options; we offer solutions using most of these methods.
