Splice - Coffee Break News for Life Scientists

This webinar discusses the following topics: Basics and principles of digital PCR (dPCR), comparisons between dPCR and qPCR, current and future applications in dPCR and platform comparison. The webinar was brought to you by National Institute of Biology Slovenia (http://www.nib.si/eng) and BioSistemika LLC (http://biosistemika.com/). National Institute of Biology and BioSistemika also organize dPCR Excellence Workshop - A practical workshop on different qPCR platforms (http://biosistemika.com/products/nib-workshop/). Participants will have an excellent opportunity to get hands-on experience with different digital PCR platforms. We would also like to thank our supporter: Splice – Coffee Break News for Life scientists (http://splice-bio.com/). BioSistemika has released sciNote - an Open Source Lab Notebook in 2016. You are all invited to subscribe for FREE at http://scinote.net/.

Why go digital in PCR?

This short tutorial demonstrates how sciNote works and takes you step by step through the sciNote features. 

sciNote is designed for life science students, researchers, laboratory managers and group leaders.

It keeps your work organized in projects. You can assign different people, add tags and set due dates. 

Each project has shortcuts, where you can see latest notifications, activity and comments from other participants. 

All the data and actions are fully traceable. With sciNote you can create custom reports with all the data, from meeting, clinical and project reports to full laboratory notebooks.

sciNote Open Source ELN: Tutorial video 

The amount of scientific data doubles every three years, but scientists mostly still rely on paper notebooks to keep track of their experiments, much like Marie Currie did 100 years ago. However, today most of generated data is digital and more than 80% of it becomes untraceable, stored on some computer. Introducing sciNote – a modern way to organize your scientific data and safely store it all in one place. Manage your projects, organize your tasks into workflows, upload results, generate reports for a meeting and share your data with your peers. You can also write your comments much like you would in a paper notebook. Access your data from anywhere with completely free sciNote cloud account or install it locally. sciNote is an open source platform so you can create your own modules, choose from a growing number of existing ones or contact sciNote team and they will develop it for you. sciNote, the easiest way to manage your scientific data.

Best pipetting practices demonstrated in 15 minutes. The webinar was brought to you by BioSistemika LLC (http://biosistemika.com/) and LOTRIC Metrology Ltd (http://www.lotric.si/en/). We would also like to thank our supporters: Gilson Inc (http://www.gilson.com/) GeneQuan by Michael W. Pfaffl (http://www.gene-quantification.info/) Splice – Coffee Break News for Life scientists (http://splice-bio.com/) BioSistemika will release sciNote - an Open Source Scientific Notebook in 2016 which will be also featured on Kickstarter in mid November. You are all invited to follow us on http://scinote.net/. We have answered the following questions that we have received during the live broadcast. Feel free to read through and if we didn't answer your question, please send an email to Niko Cemazar (niko.cemazar@lotric.si) since he is a true expert in this area. 1. Is it harmful if you place the pipette on the table in the horizontal position? No, if you place it down gently. However you should not place the pipette horizontally if you have a tip with the liquid attached to it. 2. How does heat transfer from the operator's hand to the pipette skew the debit volume? All air displacement pipetts are calibrated at the temperature of 20°C. Heating the pipette (and materials) can cause pipetting errors (lower aspirated volume). 3. Why is it important to pre-wet the tips? The liquid makes a thin layer inside the tip, so the next time you dispense, no additional liquid will stay inside the tip and consequently your pipetting will be more accurate. When pipetting larger volumes of aqueous solution we recommend you to pre-wet many times so the final humidity inside the tip is higher (approximately 3 times). 4. Is it recommended to sit on a chair or to stand up? Pipetting quality does not depend on whether you are sitting or standing, however be aware of the appropriate position to avoid health risk. 5. When picking up liquid, why would the pipette pick up more liquid if the pipette is at an angle? This is true only for the air displacement pipettes which raise the volume of the liquid by moving the air cushion inside the pipette. If you are pipetting under the angle the hydrostatic pressure which is needed to raise the liquid falls. 6. Where we can use reverse pipetting? What is the advantage of that technique? The reverse pipetting tecnique is recommended for pipetting liquids that have different viscosity or density compared to water. Some samples tend to „stick“ to the tips, causing a significant amount of sample to stay in the tips. If you are using the reverse mode pipetting, a small amount of sample stays in the tips. This reduces the error due to surface tension of the liquid being pipetted. It is also recommended to use the reverse pipetting technique when pipetting sample volumes below 10 uL. 7. Is the uncertainty the same for forward and reverse pipetting method? The pipetting uncertainty depends mostly on the user not the pipetting technique. However accuracy for reverse pipetting technique is higher when pipetting sample volumes below 10 uL. 8. What is the best way to do repetitive pipetting? For example when you need to pipette 3 times 1 ml in a tube. It is recommended to use a dispensette if you are pipetting same volumes of the same liquid. 9. Are there different pipettes for organic solvents or aqueous solutions? In case of mixtures of organic/aqueous solutions which type of pipetts shall we use? Positive displacement pipettes are used for pipetting organic solvents (for example Gilson Microman pipettes). You can use the same types of pipettes for pipetting organic/aqueous mixtures. 10. Any tips for pipetting high viscosity liquids? How do we avoid the remains of the liquid in the tip? Positive displacement pipettes are used for pipetting high viscosity liquids. 11. Should pipetting technique be different when we transfer solution to an empty vessel compared to when we transfer to a tube containing another solution and mixing both solutions? No, but make sure you discard tips each time you aspirate from the original vessel. 12. How often should the o-ring and seals be replaced? This depends on the frequency of use and aggressiveness of liquid to be delivered. The more aggressive the liquid, the sooner the o-ring and seals are damaged. Usually this should be done once per year. Make sure you follow the manufacturer‘s instructions.
