  • high sensitivity comparable with ELISA

Product Introduction

General Description

Impatiens necrotic spot virus (INSV) is a member of the tospoviruses group and have been widespread and devastating in the greenhouse industry. INSV is naturally transmitted by thrips and most commonly found in many ornamental crops. Typical symptoms of INSV infection are chlorotic or necrotic spot and chlorotic or necrotic ring spot. Growers aggressively attacking the problem can avoid crop losses by carefully inspecting new plants brought into the greenhouse, maintaining the health of plants already in the greenhouse, destroying infected plants and controlling thrips.

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.
