Catalog #: V140
Reactivity: The test reacted with all TEV isolates tested. Reaction of the ELISA is strong. Optical Density at 405nm is in arrange of 1.200 - >2.900 depending on the virus titer in the samples tested.
Sensitivity: Sensitivity of the ELISA is high. The virus can be consistently detected in infected plant tissues diluted at 1:810 - 1:2430.
Specificity: There is no cross reaction with healthy plant tissues such as tobacco, tomato or other host plants. Background is very low on all of the negative control wells.
Application: The test can be used to detect TEV in infected host plants.
It is easy and convenient To Place
Information About the Virus
Name: Tobacco Etch Virus
Vector: Transmitted by a vector; an insect; more than 10 spp.,
especially Myzus persicae; Aphididae. Transmitted in a non-persistent
manner. Virus does not require a helper virus for vector transmission.
Virus Infection: Symptoms persist and may be
strain-dependant. Symptoms varies, including necrotic leaf etching, leaf
mottling and distortion, mosaic, vein banding, malformation and necrosis,
stunting and reduced seed yield.
Geographical distribution: Spreads in the Eastern Asian region and the South and Central American region; Canada, China, Mexico, Puerto Rico, Venezuela, and the USA.
