Price: $405.00

Product Code: V1062

Size (V1062):

Description Applications Specifications


  • Purifies whole infectious non-enveloped virus & non-infectious enveloped virus
  • 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.
