PDQeX Nucleic Acid Extractor The simplicity and minimal sample manipulation requirement of the PDQeX make it an attractive option for obtaining DNA samples. Jo-Ann Stanton, PhD Department of Anatomy, University of Otago New Zealand MicroGEM's PDQeX Nucleic Acid Extractor brings together powerful enzymes with an innovative extractor cartridge and purification matrix.
This multi-stage process takes place inside the extractor cartridge. 1. The cells are lysed by a cocktail of enzymes. This cocktail varies for different substrates. For example, the lysis of leaf tissue requires a complex mixture of hydrolases and a specific program on the PDQeX to activate them.
On/Off Do not place the PDQeX close to a RF transmitter. A low power transmitter, such as a cordless or mobile phone, should be at least 2M from the PDQeX. A powerful transmitter, such as a commercial TV or radio broadcast antenna, should be at least 25M away.
