Next-generation sequencing devices (1.2012)
Sometimes it is hard to believe that next-generation sequencing platforms entered the scene only a few years ago as a high-speed alternative to the good old, but very slow, capillary Sanger sequencing machines. The progress they have made, especially in the last year, is quite impressive and there is hardly any other life science technology that evolves at such a neck-breaking speed as next-generation sequencing... more
Restriction enzymes (7.2011)
Though restriction-free cloning approaches, such as Gateway cloning and In-fusion cloning are gaining ground, classical cloning, based on restriction digestion and ligation of a DNA insert into a vector, is not past its prime and restriction enzymes are still amongst the most popular tools in life science labs. ... more
Expression vectors (6.2011)
In the early seventies Herb Boyer, Stanley Cohen and Annie Chang published two groundbreaking papers on restriction enzyme-based DNA recombination and expression of Staphylococcus aureus genes in E. coli from “hybrid plasmids”. Today almost every group keeps expression vectors in the freezer to easily express their favourite genes... more
Reporter gene assays (5.2011)
A television reporter’s job is to be at the heart of the action and to deliver an informative, precise, albeit brief, picture of what’s going on in a certain corner of the world. The same holds basically true for reporter genes ... more
Chromatography systems for life scientists (4.2011)
Chromatography columns are packed with ever smaller particles to get a higher resolution. New ultra high performance liquid chromatography systems may cope with the extreme back-pressures associated with small particle sizes ... more

Recently, two manufacturers entered the thermal cycler market with new types of PCR machines and threw down the gauntlet to the established companies ... more
Microarrays (6.2010)
Though some people predict that DNA microarrays will be displaced in the near future by next generation sequencing techniques, they are still the premier choice for most researchers performing gene expression studies. Not forgetting protein microarrays, which are on the fast lane to becoming essential tools in proteomics ... more
Antibody purification (5.2010)
Not every lab is rolling in money and is able to afford custom made antibodies on a regular basis. Others still prefer to maintain control over antibody purification to meet their special needs regarding antibody purity. Hence, purification of antibodies is still an issue in many labs ... more
Mechanical Pipettes (4.2010)
I must admit that I never made a big fuss about pipetting techniques or calibration of micropipettes during my time in the laboratory. I just grabbed a micropipette from the rack that covers the desired volume range and started pipetting. Pipetting experts may throw their hands up in horror at this improvidence and ignorance – and they are right to do so. ... more
Laboratory automation (3.2010)
Purifying proteins directly from microorganisms, cultured cells, tissues or other sources is rather nerve-racking. Since the advent of recombinant proteins and commercial kits, however, protein purification has lost its sting. ... more
siRNA Transfection (2.2010)
Transfecting cells with small interfering RNAs (siRNAs) to silence genes via RNA interference has become a very popular and widely used technique. New transfection reagents may help to optimise the efficiency of siRNA delivery. siRNA delivery. ... more
Laboratory automation (1.2010)
Workstations and liquid handlers are nothing special in most of today’s academic and industrial laboratories, whilst mobile service robots are already strolling around the floors of research institutes and knocking on laboratory doors. ... more
Protein expression systems (6.2009)
Most researchers still stick to the traditional hosts E. coli, yeast, insect and mammalian cells for the expression of recombinant proteins. There are, however, many other interesting protein expression systems available ... more
Cell Sorting (5.2009)
Sorting cells from body fluids, tissue cultures or other multicellular sources is routine in many cell biology laboratories. Most researchers rely on magnetic or electrical fields to guide the cells into the proper containers. ... more
Cell Culture Devices (4.2009)
Harry Moore, stem cell biologist and chair in reproductive biology at the University of Sheffield, UK, once dubbed cell culturing as a cross between gardening and cooking. Besides a ‘green thumb’ and a good nose for the right culture media ingredients, however, effective cell culturing also requires the proper equipment. ... more
Microscopes (3.2009)
For more than 350 years microscope developers have approached the optical diffraction barrier in tiny steps. In the last ten years, however, they have taken gigantic measures, that have led them even beyond the barrier. ... more
2D-Electrophoresis (2.2009)
Though Patrick O’Farell and Joachim Klose independently introduced Two-Dimensional Electrophoresis (2-DE) as early as 1975, it took more than two decades before 2-DE became one of the most popular protein separation techniques. ... more
TaqMan or SYBR Green? (Real-time PCR kits) (1.2009)
That's the question when it comes to the preferred detection chemistry in Real-Time PCR kits. Though there are other techniques available, most researchers performing Real-Time PCR rely on TaqMan probes or SYBR Green dyes. ... more
Uncovering Cell Relay Runners (Cell signalling assays) (6.2008)
Cell signalling is so fundamental to many cellular processes that almost any cell biologist has to deal with signal transduction. Cell signalling assays may help to keep track of the numorous signalling proteins and pathways. ... more
“Low-tech” at its Best (Blotting equipment) (5.2008)
A lot of molecular biologists still use classic blotting techniques such as Southern, northern and western blotting in their daily lab routine. Despite fancy microarray-chips, stylish real-time PCR cyclers and all the other high tech equipment found in most of today’s “Omics”-Labs. ... more
Recombineering is Gaining Ground (Cloning kits) (4.2008)
Is there anybody out there still preparing homebrewed buffers, enzyme solutions and reagents for the cloning of DNA? My guess is no! There is certainly no other molecular biology technique, where commercial kits are so firmly established as in DNA cloning. ... more
Lab-on-a-chip products (Microfluidic Chip Technology) (3.2008)
