Electrofusion, also known as cell-cell electrofusion or electrically mediated cell-cell fusion, is the fusion of two cells, mediated by electrical stimulation. Dr. Mitsugi Senda first reported this technique in 1979 when he fused two plant protoplasts by using capillary microelectrodes and applying electric current. In 1981, Dr. Ulrich Zimmerman built upon Dr. Senda’s study and […]

On the microscopic scale, the surface area of particles and materials has an important effect on their behavior. Since the surface of a material is the primary point of contact between it and the outside environment, this is where many chemical and physical effects take place. Combustion, dissolution, filtration, catalysis and other processes are sensitive […]

Laboratory spectroscopic reflectometry is a niche market within the surface metrology market. Although it is heavily tied to the semiconductor and electronics industries, its has significant applications in other areas as well. The competitors in the market are generally small, and not particularly well known outside of the surface metrology market. Spectroscopic reflectometry is used […]

Particle bombardment technology, also known as biological biolistics or bioballistics, is a nonviral, physical gene delivery method in which target cells are transfected using DNA-coated particles. Cornell University horticultural scientist John Sanford and cohorts developed the technique in the early 1980s. The technology is a very effective gene delivery method for plant cells, as it […]

When scientists bring up the subject of liquid chromatography (LC), complexity and high cost are two things that immediately come to the mind. While LC has proven to be a very useful analytical technique in the laboratory, as well as being advantageous in selected preparative and production-scale applications, it is an extremely involved technique that […]

Over the past decade, the process of visualizing and analyzing electrophoresis gels has been significantly improved, to say the least, by advancements in imaging/documentation systems and analysis software. These advanced gel-imaging systems are instrumental in comparative proteomics and biomarker discovery. Gel-imaging systems take pictures of two-dimensional (2D) electrophoresis gels and store the digital image, which […]

Gas chromatography (GC) has long been a primary analytical technique for analyzing petroleum-based fuels, but it is also used heavily in the rapidly developing biofuels industry. Petroleum-based fuels are a nonrenewable resource, and with the rapidly rising price of oil, the push to develop and expand the market for renewable biofuels is stronger than ever. […]
