I am a Clinical Research Coordinator at the U.S. Department of Veterans Affairs with a background in basic research, writing, mentoring and teaching. I studied Natural Science at Trinity College Dublin, Ireland, specializing in biochemistry with immunology and I am currently undergoing ACRP (Association of Clinical Research Professionals) certification. In my spare time, I enjoy studying HTML/CSS and SEO, doing acroyoga, making kombucha, salsa dancing, voluntary community projects and eating sushi. Feel free to send me a note with any writing opportunities or to say hello.

The presence of supercoiled plasmid DNA on a gel can be inconvenient for molecular biologists, especially beginners because it is easy to misinterpret. Read our top tips how to recognize supercoiled DNA and keep it from derailing your cloning experiments.
Cloning Strategies – a Whole Lot of Options to Choose Molecular cloning has come a long way from simple restriction digestion-ligation cloning strategies to a large number of highly efficient alternatives. Broadly classified, cloning techniques can be divided as sequence dependent and sequence independent strategies. Sequence-dependent strategies are based on restriction digestion-ligation techniques or site-specific…
If efficient cloning is what you are after, you must give Overlap Extension PCR Cloning a go! This restriction enzyme and T4 DNA ligase-free technique is faster, more reliable and easier to troubleshoot than traditional restriction methods. With only two PCR reactions required, you can insert a DNA fragment into a plasmid without spending time…
Working at a plasmid repository, I get a lot of feedback from scientists who are relieved we exist simply because that means they don’t have to request a plasmid directly from another academic lab. Either they’ve had a bad experience making requests in the past, or they really don’t know how to go about doing…
You might think Northern Blots are an old-fashioned technique. However, qRT-PCR is prone to false positives and negatives, and reviewers may require Northern Blot confirmation of your qRT-PCR results. So sometimes Northern Blots are a necessary evil.
Sometimes a clever little trick for cloning comes along that makes you just give an appreciatory “ahhh.” For me, it was TA cloning. TA cloning is not a new technique (I am showing my advanced laboratory age here), but when I discovered it, the simple elegance of the technique made me pause and wonder about…
