Best Practices for Preventing Contamination in PCR Tube Strips
Summary
- Covering PCR tube strips when not in use
- Use of nonaerosol barrier tips
- Cleaning work surfaces regularly
Introduction
PCR (polymerase chain reaction) technology has revolutionized the field of molecular biology, allowing researchers to amplify and analyze DNA sequences with unprecedented speed and accuracy. However, PCR reactions are highly sensitive and can be easily contaminated, leading to false results and wasted time and resources. In this article, we will discuss some best practices for preventing contamination when using PCR tube strips in urgent care clinics.
Cover PCR tube strips when not in use
One of the simplest yet most effective ways to prevent contamination when using PCR tube strips is to always keep them covered when not in use. Leaving the tubes exposed to the environment increases the likelihood of dust, microbes, and other contaminants settling on the tube strips and potentially influencing the results of your PCR reactions. As such, it is crucial to cover the tube strips with a lid or seal whenever they are not in use.
Use nonaerosol barrier tips
Another common source of contamination in PCR reactions is aerosols generated during pipetting. When air is expelled from a pipette tip, droplets can be released into the air, carrying potential contaminants that may interfere with your PCR results. To minimize this risk, it is recommended to use nonaerosol barrier tips, which feature a filter that prevents the passage of fluids and aerosols, reducing the chance of contamination during pipetting.
Clean work surfaces regularly
In a busy urgent care clinic setting, work surfaces can quickly become cluttered and dirty, increasing the risk of contamination during PCR procedures. To maintain a clean and sanitary work environment, it is important to regularly clean and disinfect all work surfaces, including lab benches, pipettes, and PCR machines. By maintaining a clean work area, you can significantly reduce the risk of contamination and ensure the accuracy of your PCR results.
Conclusion
Preventing contamination when using PCR tube strips is essential for obtaining reliable and accurate results in urgent care clinics. By following simple best practices such as covering tube strips when not in use, using nonaerosol barrier tips, and regularly cleaning work surfaces, you can minimize the risk of contamination and ensure the validity of your PCR reactions. By implementing these preventive measures, you can maintain the integrity of your research and provide high-quality care to your patients.
