Rebecca S. Tirabassi received her Ph.D. in Molecular Biology studying the pathogenesis of herpesviruses. After her postdoctoral fellowship, she spent 6 years working in biotech followed by 3 years as a scientist at academic institutions. She is currently the owner of Scientific Pens, LLC, a company that provides research, writing, editing and consulting services for life scientists. In addition to writing for BitesizeBio, she is the voice behind the WiKi and Blog at Advansta.com. She also writes a personal blog entitled Mad Scientist.Crazy Mom in which she talks about surviving life with 5 kids and a menagerie of animals while trying to keep her scientific mind happy (aka occasionally writing about scientific topics that interest her - like herpesviruses).

To (Science) Blog or Not to (Science) Blog

Look out technical science writing, there’s an alternative voice in town. In the past decade, bloggers have taken to their keyboards and changed the voice of the internet. With their relaxed writing styles and ability to impart wisdom in a few short paragraphs, most of the online population consumes science blogs. Although scientists are often…

What I Learned as a Grant Reviewer

A few years ago, when I was working for a biotechnology company, I got a special letter in the mail.  The NIH asked me to be an ad-hoc grant reviewer for small business grants. Although I drew these lessons from the NIH grant review process, they can probably be applied to many granting agencies.  If…

A Protein Biochemist’s Bag of Tricks

If you were to peek into a protein biochemist’s bag of tricks, what would you find? A mortar and pestle for collecting samples, some columns for isolating proteins and a mass spec instrument? Perhaps. But what about those little eppendorf tubes full of enzymes and helpful molecules? Certainly, each scientist has his/her own favorite. Here…

Dressing Up Your Oligonucleotide

Oligonucleotides are those smallish bits of DNA or RNA that we rely so heavily on for many of our molecular biology experiments. In their naked form, they are single, inert strands of DNA or RNA bases. But if you dress them up, you can increase their functionality. Here are some of the common oligo wardrobe…

How to Identify Supercoils, Nicks and Circles in Plasmid Preps

One of my favorite things to do with a student the first time they work with DNA plasmid preps is to have them run an agarose gel containing 2 samples:  uncut plasmid DNA, and plasmid DNA that has been linearized with an restriction enzyme.  I love to have them try and figure out the banding…

Six Benefits to Working in the Lab on the Weekend

I used to love working in the lab on Saturdays.  No, I didn’t spend every Saturday in the lab and yes, I did have a life outside of the lab (that’s one reason Saturday work was so great).  But there are some great benefits to working in the lab on the weekend: Beat the commute…

SuperSize It! Scaling Up Your Experiments

Life in the lab is easy-peasy when you are only prepping a handful of tubes. But what if you need to scale up to 10’s or even 100’s of samples? Scaling up your experiments can have some expected and some not-so-expected, leaving you in a lurch, consequences. Read through our tips so you aren’t caught…

The Magic Continues: TOPO Cloning

They say a magician is never supposed to tell the secret behind his tricks.  It’s a good thing then that I am a molecular biologist and not an illusionist.  Because once I learn a good trick, I feel the need to spread it like dandelion seeds floating on a breeze. That’s what inspired me to…

How to quality control check your RNA samples

You finally have your RNA in hand.  Now what? The success of downstream applications, such as microarrays and quantitative RT-PCR, relies upon having high quality, intact RNA. So it is worth your while to make sure you have a good RNA preparation before jumping into your experiments. There are three things you want to check…

Ta-Da! The Magic of Taq and TA Cloning

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…

Buying a Secondary Antibody: Why all the Choices?

So you grab a quick 5 minutes in between lectures to sit down and tackle an item on your to-do list: order a secondary antibody for an upcoming experiment.  But when you start to search your favorite secondary antibody provider’s website, you realize it is not going to be a 5 minute job.  Conjugated, F(ab’)2…

Brahe’s Battles: The Outcome

What do science and rapping have in common?  Usually not much.  Unless you happen to be Tom McFadden that is, and then rapping becomes a tool for teaching kids about science. Tom McFadden is no stranger to music and science.  Tom is a science communicator whose hit single, Regulatin’ Genes, garnered him national recognition.  In…

Counting On Your Results – Tips And Technologies For Colony/Plaque Counting

Have you ever emerged from the lab, bleary-eyed, blinking dazedly at the sun after spending hours hunched over a lab bench counting endless bacterial colonies or viral plaques? A necessary evil… I consider colony/plaque counting one of the necessary evils of working with microorganisms.  Necessary because many experiments have an endpoint that requires determining the…

What is Sterile? Find Your Way around a Sterile Tissue Culture Hood

You’ve been told that maintaining a sterile environment in a tissue culture hood is vital to preventing contamination of cell cultures. But what exactly is meant by sterile? The definition of sterile is ‘completely clean, sanitized, and free of all forms of life’. Obviously you still want your cells and/or any other organisms you are…

RNases can be Useful Too

Ribonucleases (RNases). We’ve been giving them a hard time here lately. We’ve been talking about how they are the bane of the lives of  researchers who work with RNA. And we’ve told you how to find their weaknesses and shown you a myriad of weapons that you can use to kick their RNase butts. But…

Surviving the Big Chill: Freezing and Thawing Mammalian Cells

Cryopreservation is crucial to long-term maintenance of cells. Not even the most diligent and dedicated scientist is capable of maintaining a cell line day in and day out for years. Additionally, cells can change properties, senesce, or, ooops (!) become contaminated as the length of time in culture increases. Freezing and resuscitating your cells can…
