    LyoDt® Lyophilized Power Real-Time PCR Detection Reagent For Shigella

    LyoDt® lyophilized power Real-Time PCR Detection Reagent for Shigella


    1. DESCRIPTION

    Shigella is a Gram-negative bacterium and a common pathogen causing intestinal diseases in humans. It ranks as the leading cause of infectious diarrhea pathogens in China. Transmission primarily occurs through ingestion of contaminated food (fecal-oral route), with the most common symptoms including diarrhea (watery stools), fever, and nausea.

    This product is a freeze-dried real-time PCR reagent for the detection of Shigella. It uses the highly conserved ipaH gene of Shigella as the detection target. It is a mastermix containing all necessary ingredients, except for template DNA, and it is pre-dispensed as single-test in PCR tubes for easy use. This product does not require cold chain for transportation and storage, which significantly reduces shipping cost, and eliminates possible loss by reagent wastage and aerosol contamination.

    FP-FD-02LyoDt® Freeze-Dried Real-Time PCR Detection Reagent for Shigella48 Tests
    FP-FD-02PCPositive Control1 Tube
    EP-CM-10Resealable plastic bag1 bag

    3. STORAGE AND SHELF LIFE

    Store at ambient temperature (5-30°C). It is stable for up to 12 months. Once the vacuum package is open, please store the unused products in the provided re-sealable plastic bag with the desiccants, and in the aluminum foil bag.

    CAUTION:

    The reagent pellet getting smaller is an indication of moisture seeping into the tube and the reagent is dampened. Any reagents with significant smaller pellet size than usual should be discarded or tested with positive control before use for sample testing.

    4. ADDITIONAL EQUIPMENTS & REAGENTS REQUIRED

    1) Real-time PCR instrument

    2) Pipettes and tips

    3) Nuclease-free water

    4) Nucleic acid extraction kit

    5. COMPATIBLE REAL-TIME PCR SYSTEMS

    ABI 7500/Fast, Roche LightCycler 480II, BioRad CFX96, Bioer LineGene 9600.

    6. ACCEPTABLE SPECIMENS

    Food enrichment broth, vomitus, diarrheal specimens, etc.

    7. OPERATION PROCEDURE

    1) Nucleic Acid Extraction

    Extract DNA from specimens using a proper extraction kit. It is recommended that the DNA is eluted with about 100μl of elution buffer (TE or nuclease-free H2O) in the final step of extraction. The purified nucleic acid should be used immediately or stored at -20°C.

    2) Positive Control Preparation

    The positive control can be stored at ambient temperature before rehydration for up to 12 months. It should be rehydrated before use by adding 250 μl of TE buffer or nuclease-free H2O, vortexed at low speed for 15-20 seconds, and centrifuged at low speed for 15-20 seconds. Use immediately or store at -20°C.

    3) Real-Time PCR Mix Preparation

    A) Open the vacuum package and take out the 8-tube strips containing the reagent. Check the pellet is at the bottom of the tube (Cut the number of tubes as needed if necessary). If the provided tubes are not compatible with your instrument, transfer the reagent pellet to an optical tube compatible with your instrument.

    B) Open the tubes and discard the cap(s) (not suitable for real-time PCR machines), and prepare the reaction mix on ice as below.

    Freeze-dried reagent1 tube (2μl)
    Template DNA/Positive Control/Negative Control*23μl
    Total25μl

    * Nuclease-free water can be used as negative control.

    C) Cap the PCR using caps (strips) suitable for real time PCR(not provided).

    D) Vortex the tubes at low speed for 10~15sec, and centrifuge at 3000rpm for 20sec and place them in a real-time PCR instrument.

    2) RT-PCR Setup

    Set the reaction volume as 25μl, and PCR amplification procedure as below. Collect FAM fluorescence at 60°C, and select NONE as passive reference.
