RNA-seq: Basics, Applications and Protocol

Article

RNA-seq (RNA-sequencing) is a technique that can examine the quantity and sequences of RNA in a sample using next generation sequencing (NGS). Here, we look at why RNA-seq is useful, how the technique works, and a basic protocol which is commonly used today.

Identifying Vampire Victims

News

Vampire bats feast on blood from domestic animals and can pass on blood-borne diseases such as rabies in the process. A new DNA analysis technique will make identifying the bat's victims far easier, hopefully simplifying disease control.

The Genes That Make Quorn a Fungal Food Favorite
News

The meat substitute Quorn is derived from a fungus called Fusarium venenatum. A very similar fungus, F. graminearum, is one of the world's most damaging crop diseases. A new genome study shows why one fungus makes food, and the other destroys it.

New Tools for Combating Antibiotic Resistance
New Tools for Combating Antibiotic Resistance
Article

Antibiotic resistance is a serious health problem, causing illnesses that were once easily treatable with antibiotics to morph into dangerous infections, leading to serious disability or even death. To help fight this growing threat, diagnostics companies are developing new tools and techniques that are playing a crucial role in quickly identifying infectious organisms and preventing the inappropriate use of antibiotics.

The Future for PCR Diagnostics
The Future for PCR Diagnostics
Article

The Nobel Prize winning polymerase chain reaction (PCR) technique revolutionized molecular biology on its invention in 1986 and it has done the same for medical diagnostics over the last 15 years. Being able to copy and multiply specific target DNA molecules has opened the door to diagnosing diseases across multiple areas quickly, accurately, and as time progresses at lower cost.
