Adding Your Protocols

Introduction

Creating protocols for extractions, thermal cyclers, and panels is an essential part of running PCR. Consistency is key in producing the most reliable results. In this guide, we will teach you how to create protocols for extractions, protocols for thermal cycler settings, and panels from your assays.

Panels

Introduction

Panels are composed of one or more assays that will be assigned to every sample in a batch. When you create assays, you must always create a panel referring to them in order to apply assays to your samples. To create a panel, click on “Protocols” on the menu, and select “Panels”. From there, you can then click on “Create New Panel”. For this tutorial, we will be creating 4 panels.

Creating DNA in qPCR Panel
  • Step 1 - To create a panel click on “Create New Panel” and set the name as “DNA in qPCR Panel”.
  • Step 2 - This panel will only contain DNA assays for qPCR. To do so, click on qDNA and select “Assay 1”, “Assay 2”, and “Assay 3”.
  • Step 3 - Click on “Create Panel”.

  • Step 4 - Click on “Create Panel”.
  • ...
  • Step 5 - Your list of panels should look similar to the following image.

Extractions

Introduction

Extraction protocols are another important part of processing samples for extraction. Deciding what extraction protocol to use for each batch is necessary to produce the best results. To create an Extraction protocol click on “Protocols” and select “Extractions”. From there you can then click on “Add New Protocol”. For this tutorial, we will be adding three extraction protocols. One protocol for extracting DNA, another one for extracting RNA, and one for extracting both DNA & RNA (total-nucleic).

Adding DNA Extraction Protocol
  • Step 1 - To add an extraction protocol click on “Add New Protocol” and set the name as “DNA Extraction Protocol”.
  • Step 2 - Set the Type as “DNA” and copy/paste the URL of the document containing the steps for your extraction should you have one. Otherwise, leave the field empty.
  • Step 3 - We will then select all tubes and reagents that we previously created in the Inventory Guide.
  • ...
  • ...
  • Step 4 - We must then determine the amount of tubes used per extracted sample. To do so, click on the blue tube icon next to “Tubes”. Note that we can also change the order of the tubes being displayed.
  • Step 5 - Let us set the amount per sample for “2ml Collection Tubes” as “3”, “QIAmp Mini spin columns” as “1”, and “1.7 ml Generic Centrifuge Tube” as “2”.
  • ...
  • Step 6 - Next we must determine the volume user per sample for each reagent. To do so, click on the blue flask icon near “Reagents”.
  • Step 7 - We will set Volume Per Sample (µl) for “InhibitEx Buffer” as “1000”, “Buffer AL” as “600”, “Buffer ATE” as “200”, “Proteinase K” as “25”, “Ethanol” as ”600”, “Buffer AW1” as “500”, and “Buffer AW2” as “500”. According to this Qiagen kit manual.

Adding RNA Extraction Protocol
  • Step 1 - To add an extraction protocol click on “Add New Protocol” and set the name as “RNA Extraction Protocol”.
  • Step 2 - Set the Type as “RNA” and copy/paste the URL of the document containing the steps for your extraction should you have one. Otherwise, leave the field empty.
  • Step 3 - We will then select all tubes and reagents that we previously created in the Inventory Guide. Keep note that this is a demonstration. Realistically, every extraction protocol will differ in what tubes and reagents they use as well as the amounts per sample.
  • Step 4 - We will do the exact same steps as the previous extraction protocol.
  • Step 5 - For tubes, set the amount per sample for “2ml Collection Tubes” as “3”, “QIAmp Mini spin columns” as “1”, and “1.7 ml Generic Centrifuge Tube” as “2”.
  • Step 6 - For reagents, we will set Volume Per Sample (µl) for “InhibitEx Buffer” as “1000”, “Buffer AL” as “600”, “Buffer ATE” as “200”, “Proteinase K” as “25”, “Ethanol” as ”600”, “Buffer AW1” as “500”, and “Buffer AW2” as “500”.
  • ...
Adding Total-nucleic Extraction Protocol
  • Step 1 - To add an extraction protocol click on “Add New Protocol” and set the name as “Total-nucleic Extraction Protocol”.
  • Step 2 - Set the Type as “Total Nucleic” and copy/paste the URL of the document containing the steps for your extraction should you have one. Otherwise, leave the field empty.
  • Step 3 - We will then select all tubes and reagents that we previously created in the Inventory Guide.
  • Step 4 - We will do the exact same steps as the previous extraction protocol.
  • Step 5 - For tubes, set the amount per sample for “2ml Collection Tubes” as “3”, “QIAmp Mini spin columns” as “1”, and “1.7 ml Generic Centrifuge Tube” as “2”.
  • Step 6 - For reagents, we will set Volume Per Sample (µl) for “InhibitEx Buffer” as “1000”, “Buffer AL” as “600”, “Buffer ATE” as “200”, “Proteinase K” as “25”, “Ethanol” as ”600”, “Buffer AW1” as “500”, and “Buffer AW2” as “500”.

Thermal Cycler

Introduction

Thermal cycler protocols are a major factor in producing the best results for PCR. Having the correct settings for your thermal cycler according to each plate is mandatory. To add a new thermal cycler protocol, click on “Protocols” and select “Thermal Cycler”. From there, click on “Add New Protocol”. For this tutorial, we will add two types of protocols: one for DNA and another for RNA.

Adding Thermal Cycler Protocol DNA
  • Step 1 - To add a thermal cycler protocol click on “Add New Protocol”, set the Name as “Thermal Cycler Protocol DNA”, Type as “DNA”, and Number of Cycles to 30.
  • Step 2 - Based on the following image from Millipore Sigma, we will set the Denature Temp to 94°C, and Denature Duration to 60 seconds. Annealing Temp will be 55°C with a duration of 120 seconds, and Extension Temp at 72°C with a duration of 180 seconds.
  • Step 3 - Click on “Add Protocol”.
  • ...
Adding Thermal Cycler Protocol RNA
  • Step 1 - To add a thermal cycler protocol click on “Add New Protocol”, set the Name as “Thermal Cycler Protocol RNA”, Type as “RNA”, and Number of Cycles to 30.
  • Step 2 - According to an article by ThermoFisher, we will set the Denature Temp to 70°C, and Denature Duration to 60 seconds. Annealing Temp will be 16°C with a duration of 120 seconds, and Extension Temp at 72°C with a duration of 180 seconds.
  • Step 3 - Click on “Add Protocol”.
  • ...
  • Step 3 - Your list of thermal cycler protocols should look similar to the following image.

Conclusion

Excellent! Once all your protocols have been set, you will now be ready to create a batch of samples for extraction. The Extraction Guide will teach you how to create a sample batch and assign all protocols necessary.
