The Potato virus Y^N & Potato virus Y (PVY^N/PVY) ImmunoStrip® is used to detect the presence of PVY and PVY^N in potato leaves and sprouts. PVY is a member of the Potyvirus genus known for their non-enveloped, flexuous, filamentous virus particles. ImmunoStrips® are the perfect screening tool for use in the field, greenhouse, and the lab.

The PVY^N/PVY ImmunoStrip® is a multi-line assay that not only identifies the presence of PVY, but also indicates whether the PVY present in a sample is a necrotic strain of the virus. This assay contains two test lines as well as a control line to indicate the test worked properly. One of the two test lines can detect all PVY strains while the second test line detects only PVY^N serotype strains. If both the PVY and PVY^N test lines are visible, the sample is infected with a PVY^N serotype strain. If only the PVY test line is visible, the sample is infected with a PVY^O serotype strain. If only the control line is visible, this indicates a negative result for all strains of PVY.

This test is a rapid diagnostic tool that has enhanced value for PVY disease management programs. Potato growers and inspectors can identify PVY in the field and assess whether a plant has a higher risk of developing potato tuber necrosis disease (PTNRD) associated with PVY^N recombinant strains.
