Microm DNA Isolation Kit

Norgen’s Microm DNA Isolation Kit is designed for the rapid preparation of genomic DNA from filters used for air sample collection. Various air-borne microorganisms may be trapped on the filter, including bacteria, fungi and viruses. Genomic DNA is efficiently extracted from the filter by a combination of heat treatment and a unique lysis buffer. PCR inhibitors are effectively removed during the washing steps and the purified genomic DNA is ready to use for downstream applications such as PCR and microarray analysis. The option of bead beating is also provided in order to allow for improved DNA yields for certain fungal and yeast species captured on the filter. Preparation time for ten samples is less then 30 minutes, and each kit contains sufficient materials for 50 or 100 preparations.
