A suite of techniques for virus concentration
In order to detect SARS-CoV-2 in wastewater systems, researchers need to concentrate the virus from wastewater samples. Continue reading to learn more about centrifugation solutions for virus concentration techniques:
Ultracentrifugation
• Easy set up
• Relatively fast and offers scale up options
• Eliminates scraping or washes pellets from a membrane
• Eliminates risk of clogging
• Lowers costly consumables used
Ultrafiltration
• Membrane separation technique
• Membranes can be spin-devices for a variety of volumes
• Easy solution, up to 50mL per spin-device
• Possible pretreatment of sample to avoid membrane complications
• May require high volumes resulting in more time needed to process samples
Chemical / Biochemical Precipitation
• Uses chemical or biochemical substances to precipitate the virus
• Can be adapted to different volumes
• Precipitates can be collected via centrifugation
