Learn how confocal laser scanning microscopy works, its applications, and why it’s great for samples that are too thin to section.
Contamination in your pipette can mean contamination in your experiments, making cleaning pipettes regularly critical. Here’s an easy guide on how to do it.
I’d bet that your trusty pipette is probably one the the most often used tools in the lab. But do you have any idea how to check the accuracy of your pipette? We’ll take you though how to do this in just 7 easy steps.
If you’re thinking FRAP is short for frappuccino then you need to read this article. Discover the history, how it works, and why you’d want it in your confocal toolbox
The flow cytometer that we have all grown to know and love may have only come into its own in the 1990’s, but who would have known that the first cell sorter was invented as early as the 1950’s? With the recent death of one of the key developers of fluorescence activated cell sorting (FACS),…
Power nap anyone? Depending on how long your commute is, and what type of transport you use, you could make your commute useful. If you are taking public transport, you can use that time to answer those emails you don’t have time to get to at the office/lab, or to catch up on reading some…
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…
Trying a new protocol is always a little daunting, especially if no one else in your lab is doing it. So it’s always good to find a tried and tested protocol from a reputable source before getting your hands dirty. Or at least one that can start you off in the right direction. It is…
After a very naïve start in flow cytometry thinking that published protocols will work without fault – needless to say, that did not work out in my favor – I realize now that following a few simple steps can go a long way, and will undoubtedly save you time in the end. So, here are…
What is one of the first things you do when you sit down at the flow cytometer and start looking at your cells? You start drawing polygons and setting gates. To the neophyte the gating process can look a little random – why do you exclude those dots but not these? But gating in flow…
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—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…
The great thing about being a scientist is, well… that you get to be a scientist! And it can be fun and rewarding. But being a scientist can be a nasty stressful business too. As I come to a turning point in my ‘academic career’, I find myself making mental notes of the pros and…
Looking for paraffin alternatives for tissue embedding? Find out the benefits of cryo and resin tissue embedding and how they work.
Counterstaining can have a big impact on your histology result. This short guide will introduce you to some available counterstains providing you with a few more choices.
Did you know fixation can mask antigen sites in your sample? Discover how you can unmask them and get your signal back on track!
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…
Do you know what your histology fixatives are really doing to your samples? Read on to learn what happens to tissue treated with two common fixatives.
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…
