Strip Tubes vs. PCR Tubes: Choosing the Right Option for Your Molecular Biology Experiments

When it comes to conducting molecular biology experiments, one of the crucial decisions researchers face is selecting the appropriate type of tube for their PCR (Polymerase Chain Reaction) applications. The two most common options are strip tubes and individual PCR tubes. While both serve the same fundamental purpose, they differ in design and functionality. In this blog post, we will explore the characteristics and advantages of strip tubes and PCR tubes to help you make an informed decision for your laboratory experiments.

Strip Tubes: Strip tubes are designed with multiple PCR tubes connected in a single strip. Typically, these strips contain eight individual tubes, although variants with fewer or more tubes are also available. Here are some key features and advantages of strip tubes:

  1. Efficiency and Convenience: Strip tubes offer an advantage in terms of efficiency during experimental setup. As multiple tubes are connected in a strip, it becomes easier to load samples and reagents simultaneously into all the tubes, saving time and effort.
  2. Reduction of Cross-Contamination: With strip tubes, the risk of cross-contamination is minimized. As the tubes are connected, there is no need to transfer samples between separate tubes, reducing the chances of contamination and ensuring the integrity of your experimental results.
  3. Compatibility with Multichannel Pipettes: Strip tubes are designed to accommodate multichannel pipettes, making them ideal for high-throughput applications. This feature enables simultaneous dispensing or aspirating of samples, increasing experimental throughput and reducing the overall experimental time.

PCR Tubes: PCR tubes, on the other hand, are individual tubes that can be used separately for PCR reactions. Here are some key features and advantages of PCR tubes:

  1. Flexibility in Experimental Design: PCR tubes provide greater flexibility in experimental design compared to strip tubes. Researchers can perform experiments with varying sample sizes, different types of assays, or even use different reagents in separate tubes, allowing for more customization and experimental versatility.
  2. Minimization of Sample Loss: When individual PCR tubes are used, sample loss can be minimized as each tube contains a separate seal, reducing the risk of evaporation or leakage during thermal cycling. This ensures accurate and reliable results, especially for sensitive assays.
  3. Lower Contamination Risks in Case of Mishaps: In the event of any mishap or contamination in one tube, using individual PCR tubes ensures that only that particular tube is affected, minimizing the impact on the entire experiment. This advantage is particularly crucial when working with precious or limited samples.

Conclusion: Both strip tubes and PCR tubes serve important roles in molecular biology experiments, and the choice between them depends on the specific requirements of your research. Strip tubes offer efficiency and convenience, along with reduced cross-contamination, making them suitable for high-throughput applications. On the other hand, PCR tubes provide flexibility in experimental design, minimize sample loss, and offer lower contamination risks, making them ideal for more customized experiments.

Consider factors such as the scale of your experiments, sample volume, reagent compatibility, and the level of experimental customization required when selecting between strip tubes and PCR tubes. By making an informed decision, you can optimize your PCR workflow and ensure accurate, reliable results in your molecular biology research.

What are PCR Reagents

Polymerase chain reaction (PCR) is a technique used to amplify specific regions of DNA. It involves making many copies of a specific DNA fragment using enzymes called polymerases. The process involves heating and cooling a mixture of DNA template, primers, a thermostable DNA polymerase (such as Taq polymerase), and the four deoxynucleoside triphosphates (dNTPs) required for DNA synthesis. 

The basic reagents used in PCR are: 

  • Template DNA: This is the target DNA that you want to amplify. The template DNA can be from any source, including bacteria, viruses, plant or animal cells, or even forensic samples. 
  • Primers: These are short stretches of DNA that are complementary to the ends of the region of the template DNA that needs to be amplified. Primers typically range in length from 18 to 30 base pairs. 
  • Taq polymerase: This is a thermostable DNA polymerase that can withstand the high temperatures used in PCR. Taq polymerase is isolated from the bacterium Thermus aquaticus. 
  • dNTPs: dNTPs are the building blocks of DNA and include deoxyadenosine triphosphate (dATP), deoxycytidine triphosphate (dCTP), deoxyguanosine triphosphate (dGTP), and deoxythymidine triphosphate (dTTP). 
  • Buffers: PCR requires a buffer that provides a suitable pH, salt concentration, and cofactors that are required for the activity of Taq polymerase. 
  • MgCl2: Magnesium chloride is also typically added to the reaction mix as a cofactor for Taq polymerase. 

There are also different types of PCR, including Real-time PCR, which include the use of fluorescent dyes (probe or primers) or TaqMan probe and a thermal cycler with a fluorescent detector. 

It’s important to always keep in mind that to get the best performance out of PCR reactions, it’s important to have high-quality reagents and use them under controlled conditions. We at ensure that we support your science with our products and help you to achieve best results

What are PCR Consumables?

PCR consumables are supplies that are used during the polymerase chain reaction (PCR) process. At, our signature brand of PCR consumables are from Oxford Lab Products and include items such as PCR Strip tubes, 96 Well Plates and tips. Other PCR consumables include  primers, enzymes, and reagents. They are used to amplify specific DNA or RNA sequences in a sample using the PCR process. The consumables are typically disposable and are used in one-time experiments or procedures. 

PCR consumables are used in a laboratory setting to amplify specific DNA or RNA sequences in a sample using the polymerase chain reaction (PCR) process. The specific steps involved in using PCR consumables may vary depending on the type of experiment being conducted and the specific consumables being used. However, some general steps that are involved include: 

  1. Setting up the PCR reaction: This typically involves preparing a mixture of the sample, primers, enzymes, and other reagents in a PCR tube or plate
  1. Amplifying the DNA or RNA: The mixture is then subjected to a series of temperature cycles using a thermal cycler during which the DNA or RNA is amplified through the action of the enzymes. 
  1. Analyzing the amplified product: Once the amplification is complete, the amplified DNA or RNA can be analyzed using a variety of techniques, such as gel electrophoresis or real-time PCR. 

Overall, the use of PCR consumables allows researchers to amplify specific DNA or RNA sequences rapidly and accurately in a sample, which can be used for a wide range of applications, including gene expression analysis, disease diagnosis, and genetic testing.
