CSVd Detection Kits

Chrysanthemum Stunt Viroid (CSVd) RT-PCR Kit is designed for the detection of CSVd specific RNA in a real-time PCR.

The Chrysanthemum Stunt Viroid (CSVd) is the causal agent of a disease known as chrysanthemum stunt. The viroid consists of small pieces of RNA (354 bp) that are known to be highly contagious. The main symptoms of CSVd infection are severe stunting of the plants such that they are half to two-thirds of the normal size, as well as smaller flowers and premature flowering. Symptoms of Chrysanthemum Stunt are difficult to detect in stock, however can be so severe at flowering that finished crops of flowers are unmarketable. There is no chemical that can control CSVd, therefore much effort has been made to generate chrysanthemum plants free from CSVd. Chrysanthemum Stunt Viroid SYBR Green RT-PCR Detection Kit is a rapid and sensitive CSVd detection tool which can be applicable for the early diagnosis of CSVd.

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.

Viroid

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.

PCR

The specificity of CSVd RT-PCR Detection Kit is first and foremost ensured by the selection of the CSVd-specific primers, as well as the selection of stringent reaction conditions.
The CSVd 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.
