Using Flow Cytometry for Fluorescence Resonance Energy Transfer

Using Flow Cytometry for Fluorescence Resonance Energy Transfer

A marriage of sorts Fluorescence resonance energy transfer, or FRET, is often done using a microscope, which means it can be difficult to analyze large numbers of cells in one sitting. One way to overcome this, is by combining FRET with fluorescent-activated cell sorting (FACS), giving you a high-throughput method to screen for protein interactions…

10 Favorite Online Tools for Molecular Biology

10 Favorite Online Tools for Molecular Biology

What did we do before the internet? And where would we be without handy online molecular biology tools? Apparently in the ‘olden days’ doing a simple gene or protein alignment required programs that used dynamic programming algorithms such as the Needleman-Wunsch and Smith-Waterman algorithms. These required long processing times and the use of supercomputers or…

Freeze-Thaw Cycles and Why We Shouldn’t Do It

Freeze-Thaw Cycles and Why We Shouldn’t Do It

Freeze-thaw—you know it’s bad for your samples, don’t you? While working in the lab, you have most likely heard someone say ‘aliquot your protein/cells/DNA/RNA to avoid too many freeze-thaw cycles.’ But do you actually understand why? You probably thought that avoiding freeze-thaw cycles had something to do with damaging cell structure as well as proteins…

I’m Sticking With You: Four Coatings To Help Cells Stick To Microscopy Slides

I’m Sticking With You: Four Coatings To Help Cells Stick To Microscopy Slides

Have you ever isolated a great little population of cells after days or months of trying, got truly excited about doing some immunofluorescence with them only to find out (at the very end) that all your cells washed away?! If this has happened to you, then look no further; we will introduce you to some…

Getting Those Chromosomes To Spread- A Beginner’s Guide To Meiotic Chromosome Spreads

Getting Those Chromosomes To Spread- A Beginner’s Guide To Meiotic Chromosome Spreads

So you want to do meiotic spreads do you? Maybe it’s to check if meiosis is progressing the way it should, or even to look for sites of DNA damage. Whatever the case this technique can be a little tricky at first, but once you learn a few tricks it’s like riding a bicycle- so…
