Workflow and Sample Preparation
Using the QIA Symphony DSP Virus Pathogen Kit involves a standardized workflow that ensures sample integrity and maximizes nucleic acid yield. Laboratories typically follow these steps
Step 1 Sample Lysis
Samples are first treated with a lysis buffer provided in the kit, which disrupts viral ptopics and releases nucleic acids. This step ensures that RNA and DNA are available for binding to the extraction matrix.
Step 2 Binding and Washing
Nucleic acids bind to magnetic ptopics or columns included in the kit, while contaminants and inhibitors are washed away. This step is automated on the QIA Symphony instrument, reducing the risk of human error.
Step 3 Elution
After washing, purified nucleic acids are eluted in a suitable buffer, ready for downstream molecular analysis. The eluted material can be used immediately for PCR, sequencing, or stored at low temperatures for later use.
