Viraffinity™   Virus and Viral Component Isolation

 

Virus Enrichment & Purification


•  Purifies whole infectious non-enveloped virus & non-infectious enveloped virus18. Viraffinity_1.PNG

•  Complements ultracentrifugation, for viral proteomic enrichment 350X from 

   plasma (Ref: Fragnoud et al, 2016)

•  Isolates antigenic virions, enveloped and non-enveloped

•  Enriches for viral nucleic acids

•  Prepares viral samples for subsequent detection and analysis

 

Viraffinity™ is a unique water-insoluble elastomeric polyelectrolyte that has been engineered for the capture and recovery of viruses. Applications include: purification of whole infectious non-enveloped virus, virions, viral components, and sample preparation for subsequent detection and analysis. 


Viraffinity™ is directly added to the sample that is then mixed and centrifuged. The centrifuged pellet contains polyelectrolyte-bound viruses that can then be recovered using a moderately alkaline pH solution. Viraffinity™ is supplied as a suspension reagent ready for use. Simply pipette the suspension into the sample at the appropriate ratio, typically 1 volume of Viraffinity™; to 4 volumes sample. Viraffinity™ is also supplied as the enabling component of the ViraPrep™ application kits.
