Catalog #:  V208
Source Antibody:  A rabbit polyclonal antibody for capture and and a monoclonal antibody as detection.
Test Format:  TAS ELISA                                   

Reactivity:  The test reacted with all GLRaV-2 isolates tested. Reaction of the ELISA is moderate strong.  Optical Density at 405nm  is in arrange of 0.395 - >2.100 depending on the virus titer in the samples tested.

Sensitivity:  Sensitivity of the ELISA is moderate high.  The virus can be consistently detected in infected plant tissues diluted  at 1:10 -1:90.

Specificity:  There is no cross reaction with healthy plant  tissues such as grapevine or other host plants. Background is low on all of  the negative control wells.

Application:  The test can be used to detect GLRaV-2 in infected host plant tissues.

Information About the Virus

Name:  Grapevine Leafroll Associated Virus - 2
Acronym:  GLRaV-2
Synonyms:  Six viruses, designated grapevine leafroll-associated 1,2,3,5,6 and 7 closteroviruses have been associated with grapevine leafroll disease.
Group/Genus:  Closterovirus

Vector:  Transmitted by Pseudococcus longispinus, Planococcus ficus (GLRaV-3).
Transmission: Virus is not transmitted by mechanical inoculation. Virus transmitted by grafting.
Main natural host plants: Vitis vinifera.

Virus Infection Symptoms:  Rolling and discoloration of leaves (reddish-purple in red-fruited, and yellowish in white-fruited cultivars), especially conspicuous in mate summer and early autumn in intolerant cultivars. Symptomless infection in some American Vitis spp. and hybrids.
Diagnostically susceptible host species and symptoms: Vitis vinifera cvs Cabernet, Pinot Noir, Mission, Gamay - leafrolling and discoloration.

Geographical distribution: Probably distributed worldwide.
