Hey there! I’m a supplier of deep well plates, and I often get asked about how to store samples in these bad boys for the long haul. So, I thought I’d put together this blog to share some tips and tricks based on my experience in the biz. Deep Well Plate
Why Deep Well Plates?
First off, let’s talk about why deep well plates are so popular for sample storage. These plates are like the Swiss Army knives of the lab world. They’ve got a high capacity, which means you can store a ton of samples in a relatively small space. Plus, they’re super versatile. You can use them for all sorts of applications, from cell cultures to chemical reactions.
And here’s the kicker: deep well plates come in different formats, like 96-well or 384-well, so you can choose the one that’s right for your needs. Whether you’re running a small-scale experiment or a large-scale study, there’s a deep well plate out there for you.
Preparing Your Samples
Before you start loading your samples into deep well plates, you gotta make sure they’re in tip-top shape. First, you need to centrifuge your samples to get rid of any debris or air bubbles. This will ensure that your samples are evenly distributed in the wells and that you get accurate results.
Next, you need to choose the right buffer for your samples. The buffer will help maintain the pH and osmolarity of your samples, which is crucial for their stability. Make sure you choose a buffer that’s compatible with your samples and the storage conditions you’ll be using.
Finally, you need to label your samples clearly. This might seem like a no-brainer, but you’d be surprised how many people forget to do this. Use a permanent marker to label the wells with the sample name, date, and any other relevant information. This will make it easier for you to keep track of your samples and avoid any mix-ups.
Loading Your Samples
Now that your samples are ready, it’s time to load them into the deep well plates. You can use a pipette or a multichannel pipette to transfer your samples from the tubes to the wells. Make sure you dispense the samples slowly and steadily to avoid any spills or splashes.
If you’re using a multichannel pipette, make sure you align the tips correctly with the wells. This will ensure that you dispense the same volume of sample into each well. And don’t forget to change the pipette tips between samples to avoid cross-contamination.
Once you’ve loaded all your samples, you need to seal the deep well plates. You can use a heat sealer or an adhesive film to seal the plates. Make sure you seal the plates tightly to prevent any evaporation or contamination.
Choosing the Right Storage Conditions
The storage conditions you choose for your samples will depend on a few factors, like the type of samples you’re storing and how long you need to store them. Here are some general tips to keep in mind:
- Temperature: Most samples need to be stored at low temperatures to maintain their stability. You can store your samples in a freezer at -20°C or -80°C. If you’re storing your samples for a long time, it’s best to use a -80°C freezer.
- Humidity: High humidity can cause your samples to degrade, so it’s important to store your samples in a dry environment. You can use a desiccator or a humidity-controlled storage cabinet to keep your samples dry.
- Light: Some samples are sensitive to light, so it’s important to store them in the dark. You can use opaque deep well plates or cover the plates with aluminum foil to protect your samples from light.
Monitoring Your Samples
Once you’ve stored your samples in the deep well plates, you need to monitor them regularly to make sure they’re still in good condition. Here are some things you can do to monitor your samples:
- Check the temperature: Make sure the temperature in the freezer or storage cabinet is stable. If the temperature fluctuates, it can cause your samples to degrade.
- Check the seals: Make sure the seals on the deep well plates are still intact. If the seals are broken, it can allow air and moisture to get into the plates, which can cause your samples to degrade.
- Check the samples visually: Take a look at your samples under a microscope or with the naked eye to make sure they’re still in good condition. If you notice any changes in the color, clarity, or consistency of your samples, it could be a sign that they’re starting to degrade.
Troubleshooting
Even if you follow all the steps above, you might still run into some problems with your samples. Here are some common problems and how to fix them:
- Evaporation: If you notice that your samples are evaporating, it could be a sign that the seals on the deep well plates are not tight enough. Try resealing the plates or using a different type of seal.
- Contamination: If you notice that your samples are contaminated, it could be a sign that you didn’t follow proper aseptic techniques when loading the samples into the plates. Try cleaning the plates and starting over again.
- Degradation: If you notice that your samples are degrading, it could be a sign that the storage conditions are not right. Try adjusting the temperature, humidity, or light conditions to see if that helps.
Conclusion
Storing samples in deep well plates for the long term can be a bit tricky, but it’s definitely doable. By following the tips and tricks outlined in this blog, you can ensure that your samples stay in good condition for as long as you need them.
