Catalog #:  V140
Source Antibody:  Rabbit polyclonal antibody for both capture and detection.
Test Format:  DAS ELISA                                   

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.

Information About the Virus

Name:  Tobacco Etch Virus
Acronym:  TEV
Synonyms:  datura Z virus, tobacco severe etch virus, tomato etch virus
Group/Genus:  Potyvirus

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.
Transmission: Virus transmitted by mechanical inoculation; not transmitted by seed.
Main host plants: Many natural host plants including Cassia obtusifolia, Capsicum annuum, Datura stramonium, Lycopersicon esculentum, Nicotiana tabacum,  and Physalis spp.

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.
Diagnostically susceptible host species and symptoms: Chenopodium album, C. amaranticolor and C. quinoa - local chlorotic or necrotic lesions, not systemic; Datura stramonium - systemic mosaic, ringspots, rugosity and leaf malformation

Geographical distribution: Spreads in the Eastern Asian region and the South and Central American region; Canada, China, Mexico, Puerto Rico, Venezuela, and the USA.
