    Abcam's PEG Virus Precipitation Kit provides an easy, convenient and time-saving method to concentrate viruses without ultra-centrifugation. The kit can be used for small lab samples or large scale virus preparation with high yield and high viral titer. The kit can be used to concentrate retroviruses, baculoviruses, lentiviruses, and phages etc. in cell culture medium or environmental samples. Viruses can be concentrated over 100 fold. An optimized Virus Re-suspension Solution is provided to maximize viral recovery by 40-100% depending on the virus type and sources. The whole process uses non-toxic reagents. The concentrated virus can be used for infection, viral DNA or RNA purification, etc.

  • Concentration of baculovirus: Low titer baculovirus (10 ml) expressing human Granzyme B was precipitated following the kit protocol and the precipitate was suspended in 1 ml of Virus Re-suspension Solution. Both low titer and precipitated baculovirus was subsequently used to infect SF9 Insect cells. The activity of recombinant Granzyme B secreted into the culture medium by low titer and precipitated baculovirus infected insect cells was monitored using ab157403 - Granzyme B Activity Assay Kit (Fluorometric).

You can use gentle sonication in a water bath to completely dissociate the pellet and then resuspend it in the virus resuspension solution. Make sure the sonication does not build heat in the sample.

This PEG Virus Precipitation Kit (ab102538) can be used to concentrate viruses and is not specific to a particular type. Although we list retroviruses, baculoviruses, lentiviruses, and phages on our datasheet, the list does not stop there and this kit ...

That's good news! Let me know if you have any other questions.

1) We have not tested circovirus-but based on literature I think it should precipitate circovirus 2) Our kit formulation favors virus precipitation, but the purity (whether some proteins are co-precipitated) may depend on what is in the sample.
