Burning bright: a brief history of ethidium bromide DNA staining

For several decades, Ethidium Bromide (EtBr) was the molecular biologist’s default dye for DNA staining. Now, EtBr is being consigned to the history books. It’s time to have a historical look at where it all started.

How to Deal with Stress of a Research Project Examination

A scientist’s life is full of stress. An experiment is not working— stress, experiment working but producing results opposite to the previous one— stress, somebody using the last of the reagent you need now— more stress. But these are unexpected stresses, small and overcome easily. The ‘planned stresses’ such as meetings with your supervisor or…

What To Do About Rust in Your Incubator

Ideally, your tissue culture incubator should be polished stainless steel, gleaming and immaculate like a surgical theatre. And I am sure you keep it in order, like new. It’s just sometimes you start in a lab where the incubators already have brown spots – rust. There’s Rust in My Incubator! Usually rust occurs because of…

More Than a Clever Name: Northern Blots

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.

Sanger Sequencing: How the Genome Was Won

I’ve never run a sequencing gel in my life, but people around me did, and they spent a lot of time on getting it just right. Although the principle described by Sanger in 1975 sounds straightforward (1), sequencing gels are very long and very thin – less than a millimeter thick! They were easy to…

Top Tips for Yeast Microscopy

Microscopy is one of the fun parts of working with yeast. If you fix your cells, you can get a snapshot of the structures. Live cells microscopy using fluorescent proteins tagged proteins is even better, as you can see the dynamics and cell machinery working before your own eyes. Light Microscopy to Check for Contamination…

Top Tips on How to Prevent Cell Line Cross-Contamination

Recently we wrote an article about widespread cell culture contamination and how to detect it. This follow-up article will provide practical tips on avoiding cross-contamination in the first place. Be Cautious While Working The first way of cross-contaminating cultures is by accidentally mixing two cultures together, which may lead to an unintended co-culture or the displacement…

Gene Synthesis: Cloning of The Future?

I remember the time when elves and wizards walked the Earth and DNA oligonucleotide synthesis was $5 a nucleotide. But the world has changed, nobody thinks twice about ordering an oligo. Whole gene synthesis, which is synthesis of long oligos and their assembly into a very, very long oligo. With prices of around 25–35 cents per…

Cell Culture: a Case of Mistaken Identity

While working in a UK university, I met a researcher who loved Italy much more than the UK. I asked her why she had left her favourite country. She told me that before coming to the UK, she had a 2-year fellowship in Italy where she was getting some promising results and had the chance…
