Annex Virus Purification (VP) Resin 

Protein Ark developed Annex VP Resin chromatography media specifically for virus purification; Comprising dual layer agarose beads with an inert external shell with tightly controlled pore size and internal polyfunctional ligands for rapid high capacity binding of impurities. 

Large particles, such as viruses, are excluded from the beads. The beads can be packed in a column where the virus will pass through the column bed and collected in the flow through fraction, whilst impurities will be captured within the beads. This affords a very gentle purification process resulting in efficient clean up and high recovery of active virus particles. 

Annex VP Resin is available in three different outer shell pore sizes, and two different impurity binding chemistries (see table below).
