DIRECTION FOR USE Rev003, Mar 2020 Kylt® Coryza PCR Detection Revision No. Amendments 003 New Layout A. General Kylt® Coryza PCR Detection kits are intended for the specific detection of the etiological agent of Infectious Coryza (Avibacterium paragallinarum). The kits are suitable for the analysis of samples from birds, such as swab samples and exsudates of sinus infraorbitalis, trachea, lung and air sacs as well as material derived from cultural processes of the aforementioned samples. Kylt® Coryza comprises all reagents and controls of Coryza. The qualitative testing with Kylt® Coryza kits is based on Polymerase Chain Reaction (PCR). By using specific oligonucleotides the target gene of interest in a samples is specifically amplified. Following amplification, the PCR reaction is analyzed by agarose gel electrophoresis for qualitative test results. By analyzing the detection of the target gene in the samples and the Negative Control and Positive Control per run the Coryza-specific status of a sample can be evaluated in the end. This way, results can be achieved within a few hours after sample receipt. These kits were developed for use by trained laboratory personnel following standardized procedures. This Direction For Use must be followed strictly. Kylt® Coryza | PCR Detection 2/7
B. Reagents and Materials The following Kylt® Coryza kits are available and comprise the following reagents: 100 Reactions 25 Reactions Reagent Colour of Lid Article No 31048 Article No 31049 Store at 2x PCR-Mix white 4 x 280 µl 1 x 280 µl ≤ -18 °C 10x Loading Dye white 4 x 60 µl 1 x 60 µl ≤ -18 °C Primer-Mix white 4 x lyophilizate 1 x lyophilizate ≤ -18 °C (final 160 µl each) (final 160 µl each) Positive Control red 4 x lyophilizate 2 x lyophilizate ≤ -18 °C (final 20 µl each) (final 20 µl each) Negative Control blue 1 x 1 ml 1 x 1 ml ≤ -18 °C After receipt, the components are immediately stored at the corresponding temperatures listed above. Avoid repeated freezing and thawing of all the reagents and keep them thawed as short as possible. If occasional processing of few samples only is expected you may prepare appropriate aliquots of reagents before storage at ≤ -18 °C. Prepare aliquots in such a way that freeze-thaw-cycles are reduced to a maximum of three. The Negative Control can alternatively be stored at +2°C to +8°C. The components are to be used within the indicated shelf life (see box label). The components of different batches may not be mixed. Before its first use, rehydrate the Positive Control: add 20 μl of Negative Control per vial, briefly incubate at room temperature and mix thoroughly by repeated vortexing. It is recommended to generate aliquots of suitable volumes and store them at ≤ -18 °C. Before its first use, rehydrate the Primer Mix: add 160 μl of Negative Control per vial, briefly incubate at room temperature and mix thoroughly by repeated vortexing. It is recommended to generate aliquots of suitable volumes and store them at ≤ -18 °C. C. Equipment and Reagents not included This detection method can be used on all commercially available PCR thermal cyclers. Apart from the disposables, the following further devices are needed and are not included in the Kylt® Coryza kits: DNA preparation kit / protocol (e.g. Kylt® DNA Extraction-Mix II or Kylt® RNA / DNA Purification products) Table top microcentrifuge Micropipettes covering volumes of 1 µl to 1000 µl Centrifuge for PCR tubes or plates PCR thermal cycler Equipment, media and disposables for agarose gel electrophoresis We recommend the exclusive use of certified Nuclease-free disposables as well as powder-free protective gloves. Please wear gloves during the entire experimental procedure. Gloves need to be changed frequently, especially after spillage or suspected contaminations. Kylt® Coryza | PCR Detection 3/7
D. Control Reactions The Positive Control allows for control of the specificity and efficiency of the reagents and the reaction itself, including the performance of the PCR and of the PCR thermal cycler. The Negative Control allows for exclusion of contaminations. The sample testing is only valid if both, Positive and Negative Controls, are used and verified for validity in every PCR run. E. Protocol (see also „Protocol At A Glance“ at the end of this Direction For Use) The overall protocol of the analysis consists of the following main workflow: 1. Sample Preparation 2. DNA Preparation 3. Reaction Setup and Amplification (PCR) 4. Agarose Gel Electrophoresis 5. Data Analysis – Validity and Qualitative Result We recommend proceeding through the protocol without interruption to avoid potential degradation of the processed samples and reagents. If necessary, you may store the final DNA preparation at ≤ -18 °C until further processing. Avoid repeated freezing and thawing of the DNA preparations. 1. Sample Preparation We recommend pooling of at most five samples or samples from five individuals, respectively, per DNA preparation. Pool swabs in a sufficient volume of sterile buffer (e.g. 1 ml of Normal Saline or 0.1 x TE), let the swabs soak for an adequate period of time and finally wash out the swabs by thorough pulse-vortexing. The supernatant is used for DNA preparation. For Kylt® DNA Extraction the supernatant is (fully) transferred to a conical screw cap tube (please refer to 2 "DNA Preparation"). Small swabs may directly be immersed in lysis buffer, if applicable. Material derived from cultural processes, i.e. colony material, is directly transferred into respective tubes, such as conical screw cap tube; therefore a little amount of a single colony is picked with a sterile loop wire or sterile pipette tip and transferred to the tube.

2. DNA Preparation a) Kylt® DNA Extraction (requires Kylt® DNA Extraction-Mix II) For detailed information, please refer to the Direction For Use of Kylt® DNA Extraction-Mix II. b) Kylt® RNA/DNA Purification products All kinds of sample matrices, including pure isolates and swabs, may be processed with Kylt® RNA/DNA Purification products (please refer to chapter F “Related Products”). For detailed information on the DNA preparation process, please refer to the respective Direction For Use. c) Alternative methods All kinds of sample matrices, including pure isolates and swabs, may be processed with appropriate DNA preparation kits or appropriate in-house methods. For detailed information on the DNA preparation process, please refer to the Direction For Use or Standard Operating Procedure of the specific kit or in-house method, respectively. 3. Reaction Setup and Amplification (PCR) Before each use, briefly vortex and spin down the 2x PCR-Mix, rehydrated Primer-Mix and Negative Control. To determine the total number of reactions needed, count the number of samples and add two more for the Negative Control and the Positive Control. Prepare a Master-Mix contraining the 2x PCR-Mix, 10x Loading Dye and the Primer-Mix for the appropriate number of reactions. Then add 18 μl of the Master-Mix to reach of the PCR tubes or wells of plate ("cavity"). The PCR is set up in the given order: Volume (µl) Reagent per Reaction e.g. n=7 2x PCR-Mix 10 µl 70 µl 10x Loading Dye 2 µl 14 µ Primer-Mix 6 µl 42 µl Total Master-Mix 18 µl 126 µl dispense 18 µl per reaction Template (Negative Control / DNA preparation / Positive Control) 2.0 µl Total Reaction 20.0 µl Kylt® Coryza | PCR Detection 5/7
Add 2 μl of the Negative Control to the corresponding cavity and seal it individually, if possible. Add 2 μl of each sample DNA to the corresponding cavities and seal them individually, if possible. To minimize risk of potential cross-contaminations, 2 μl of the Positive Control are added to the corresponding cavity after all previous samples and control reactions are set up. Before each use, briefly vortex and spin down the rehydrated Positive Control (see also chapter B “Reagents and Materials”). If not already done, finally seal the cavities. It is recommended to briefly spin them down before the start of the PCR run. Place the cavities in the PCR thermal cycler and run the test with the parameters as given below. Step No Description Temperature Duration 1 Activation of Polymerase 94 °C 3 min 2 Denaturation 94 °C 30 sec 3 Annealing 57 °C 30 sec 35 cycles 4 Extension 72 °C 60 sec 5 Post-PCR cooling (optional) 7 °C hold Please follow the specified instructions of your PCR thermal cycler as recommended by the manufacturer. 4. Agarose Gel Electrophoresis General The expected Coryza-product size is 510 bp, you may run any standard agarose gel electrophoresis method appropriate for this product size. An appropriate method is described in the following: Prepare a 2% standard agarose gel for separation of the DNA sample after PCR amplification. The PCR reactions already contain loading buffer including electrophoresis tracking dyes that migrate at approximately 4 kbp and 50 bp and are ready for loading on agarose gel following PCR. Load the wells of agarose gel electrophoresis with 5 µl of the PCR reactions from the DNA sample(s), Positive Control and Negative Control, respectively. Load at least an additional well of agarose gel with an appropriate volume of e.g. an 100 bp reference DNA ladder. Make notes of the position of sample(s), controls and ladder. Run the electrophoresis at a voltage of approximately 15 V/cm (the distance in cm refers to the distance between electrodes) for 45 min to 60 min. Following electrophoresis, stain the gel with appropriate amount of nucleotide / intercalating dye (e.g. ethidium bromide, GelRed Nucleic Acid or SYBR green) and visualize by using the corresponding technique. For more details, please refer to the Direction For Use of the dye. Kylt® Coryza | PCR Detection 6/7
5. Data Analysis – Validity and Qualitative Result The readily stained agarose gel must give discrete bands of expected sizes for control reactions and the reference DNA ladder. The actual PCR test analysis starts with the validity check of the entire PCR run. Therefore, check the results of Positive Control and Negative Control for presence / absence of expected product size for Coryza. Afterwards, the specific status of Coryza of each sample is analyzed by looking for presence / absence of the expected product size. Test Evaluation The PCR test run is only valid, if the Negative Control is negative and the Positive Control is positive with regard to the expected Coryza-specific product size of 510 bp. A sample is negative for Coryza, if absence of Coryza-specific product with size of 510 bp is observed. A sample is positive for Coryza, if presence of Coryza-specific product with size of 510 bp is observed. G.
