CTiVd Detection Kits

Coconut Tinangaja Viroid (CTiVd) RT-PCR Kit is designed for the detection of CTiVd specific RNA in a real-time PCR.

Coconut Tinangaja Viroid (CTiVd) RT-PCR Kit is designed for the detection of CTiVd specific RNA in a real-time PCR based on the use of technology. This kit is designed for research use only and not for use in diagnostic procedures. The detection of CTiVd specific RNA is based on one-step RT-PCR providing a simple, reliable and rapid result for the detection of CTiVd infection. CTiVd TaqMan RT-PCR Kit includes a PCR control to monitor for PCR inhibition, and to validate the quality of the sample and the detection result. The CTiVd RT-PCR Kit comprises Master Mix for the target and PCR control detection, Primer & Probe Mix, as well as a positive control and a negative control (nuclease-free water) to confirm the integrity of the kit reagents.

1. Before use, suitable amounts of all components should be completely thawed at room temperature, mixed by gentle vortexing or by pipetting, and centrifuged briefly.
2. Work quickly on ice.
3. The recommended minimum number of DNA samples tested per PCR run is 6.

1. Follow universal precautions. All specimens should be considered as potentially infectious and handled accordingly.
2. Ensure that a suitable lab coat, disposable gloves, and protective goggles are worn when handling specimens and kit reagents.
3. Use sterile pipette tips with filters. Use proper pipetting techniques and maintain the same pipetting pattern throughout the procedure to ensure optimal and reproducible values.
4. Ensure that appropriate specimen collection, transport, storage, and processing techniques are followed for optimal performance of this test.

Coconut tinangaja viroid (CTiVd) is associated with tinangaja disease, a lethal disease of coconut palm which was first described in 1917 in Guam. This disease resembles coconut cadang-cadang disease, caused by a coconut cadang-cadang viroid (CCCVd), which occurs in the Philippines. The two viroids share about 65% overall sequence homology. Typical symptom of CTiVd include yellow spots on the leaves and the production of small, scarified, elongated nuts lacking kernels.

PCR

The CCCVd primers were checked for possible homologies to all plant viroids in GenBank published sequences by sequence comparison analysis.

All kit components should be stored at -20°C upon arrival. Repeated thawing and freezing (> 2 x) of the Master Mix and Positive Control should be avoided, as this may affect the performance of the assay. If the reagents are to be used only intermittently, they should be frozen in aliquots. All reagents can be stored for 1 year at -20°C without showing any reduction in performance.
