Overview

• Detection kits for Vibrio cholerae
• Available in TaqMan format for analysis
• CE-IVD marked version available for in vitro diagnostic use

Vibrio cholerae is a comma-shaped, gram-negative bacterium. It is the cause of cholera in humans, which affects the upper small intestine. Transmission of the disease is mainly through contaminated food or water. Human subjects affected by cholera exhibit severe watery diarrhea and vomiting, caused by the cholera toxin produced by the bacterium. Many cases of cholera are life-threatening, as diarrhea and associated vomiting can lead to rapid dehydration and electrolyte loss. Even with the extensive research on its epidemiology, cholera still affects over 5 million people per year worldwide.

Storage Conditions and Product Stability
All kit components can be stored for 2 years after the date of production without showing any reduction in performance.

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.

Introduction

Hipure viral RNA kit is suitable for purifying viral RNA from samples such as cell-free body fluid or culture medium. The kit is based on silica gel column purification technology. It requires no toxic phenol chloroform extraction and time-consuming alcohol precipitation in the extraction. The whole extraction process takes only 25 minutes. The kit is suitable for extracting viral RNA from 1-140µl cell-free fluid samples such as serum, plasma, cell-free body fluid or culture medium. The product has successfully extracted hepatitis B A/C, hepatitis C RNA, SARS and HIV. The obtained RNA can be directly used for RT-PCR, Northern hybridization and virus detection.

Principle

Hipure silica gel column is based on glass fiber filter membrane with high binding force. Under the condition of high concentration of ionizing agent (such as guanidine hydrochloride or guanidine isothiocyanate), the filter membrane can adsorb nucleic acid through hydrogen bond and electrostatic, while protein and other impurities are not adsorbed and removed. The filter membrane adsorbed with nucleic acid is washed to remove the residual protein and salt. Finally, the nucleic acid adsorbed on the filter membrane can be washed out with low salt buffer (such as buffer TE) or water. The obtained nucleic acid has high purity and can be directly used in various downstream experiments.

The sample is homogenized and lysed in the lysate, and RNA is released into the lysate. The high concentration of guanidine isothiocyanate contained in the lysate denatured and inactivated endogenous or exogenous RNase, while RNA is protected from degradation. The lysate is centrifuged to remove insoluble impurities. After adding ethanol to adjust the binding conditions, it is transferred to the column for filtration. RNA is adsorbed on the membrane of the column, while protein is removed without adsorption. The column is washed with buffer VHB to remove protein and other impurities, washed with buffer RW2 to remove salt. Finally the RNA is eluted by RNase free water. The eluted RNA can be directly used in RT-PCR, Northern blot, poly-A purification, in vitro translation, etc.

Advantages

• Fast – several samples can be extracted in 20 minutes by column method
• High quality – high purity total RNA can be directly used in various sensitive downstream applications
• Safe – no phenol chloroform extraction required
• Sensitive – RNA can be recovered at the level of PG
• High yield – carrier RNA contained in the product maximize the recovery of trace nucleic acid

Storage and Stability

Carrier RNA should be stored at 2–8°C upon arrival. However, short-term storage (up to 12 weeks) at room temperature (15–25°C) does not affect their performance. The remaining kit components can be stored at room temperature (15–25°C) and are stable for at least 18 months under theseconditions
