CDIATM Potato Virus X (PVX) Test Cassette (DTSPV7)

Intended Use

The test can be simply used to on-site and rapid detect PVX in infected potato leaves, tuber eyes, sprouts, and stems, without requiring any special equipment or expertise to run.
  • infected potato leaves, tuber eyes, sprouts, stems
  • Cassette
  • high sensitivity comparable with ELISA

Product Introduction

General Description

Potato virus X is the type member of the Potexvirus family of plant viruses. The virus can cause symptoms of chlorosis, mosaic, decreased leaf size, and necrotic lesions in tubers. It is transmitted mechanically, not by an insect vector. The most important way to control this virus is to plant certified seed.

Principle Of The Test

The development of rapid test strips is based on Lateral Flow Device (LFD) technology using specific antibodies. A LFD format consists of antibody-coated latex beads latex (or colloidal gold) which will bind the specific pathogen antigen absorbed from the plant extract. The agglutination is accumulated at a specific location by the presence of a line of target specific antibody, which immobilises the agglutinated latex whilst allowing the background reagents to be washed away by continued flow along the membrane. The membrane contains a strip of target-specific antibody, test strip and a strip of another antibody that binds to the specific antibody, control strip. Latex beads containing bound antigen are trapped on the test strip leaving a visible line. Surplus latex beads that do not contain antigen are trapped on the control strip showing that the assay has worked. This provides a non-subjective and clear read out of a positive result against a low background.
