Plasmid vs. Genomic DNA Extraction: The Difference

By Suzanne Kennedy | June 21, 2023

Most experiments start with a piece of DNA—either plasmid DNA or genomic DNA. And your downstream uses for it dictate how much you need, what contaminants you can tolerate, and your extraction and purification methods. In this article, we explain the key differences between plasmid and genomic DNA extraction methods.

5 Types of Difficult Lab Supervisor and How to Handle Them

By Suzanne Kennedy | January 21, 2021

The lab is a melting-pot full of workers from different cultures and backgrounds, so some conflicts of personality are inevitable. However, when the lab head is the person that you are struggling to get along with, it can make your life a lot harder. Check out some different personality types and get advice on how to work with them effectively.


The Key to Unlocking DNA from FFPE Tissues

By Suzanne Kennedy | July 9, 2016

Formalin fixed paraffin embedded (FFPE) tissues are valuable samples that typically come from human specimens collected for examination of the histology of biopsies for the detection of cancer. But each sample contains much more information just waiting to be unlocked. Despite the tiny sample size, DNA can be extracted from the tissue sections and used…

There’s No Need To Be Paranoid About RNA Purification

By Suzanne Kennedy | July 9, 2016

RNA purification may be a common procedure in molecular biology but it is by far the one that people fear most. Why? Dreaded RNase. It’s everywhere… all over your bench and pipettes, and floating in the air, waiting for the chance to creep into your prep, shred your RNA into nucleotides, and ruin a day’s…

When Glycogen is not Your Friend – Isolating RNA from Glycogen-Rich Tissues

By Suzanne Kennedy | April 16, 2014

Bitesize Bio has had a lot to say about RNA isolation, mainly because it is one of the most anxiety-producing requirements for molecular biology; especially when you are first starting out (although isolating proteins from complex samples like soil and stool is far more difficult, let me tell you.  But that’s a future post.)  We’ve…

Troubleshooting RNA Isolation

By Suzanne Kennedy | March 19, 2014

As widely used as it is, isolating RNA remains one of the more finicky protocols. Just about anyone who has performed the technique has their own personal tips and tricks to successfully isolate intact RNA from their samples with consistency. Although RNA can be somewhat unpredictable since it is so labile, there are a few…
