A team from the University of Camerino in Italy, recently used LC-MS/MS to identify killer toxins to discover new opportunities for controlling Malaria - a deadly infectious disease common in a number of tropical and subtropical countries.


Analyzing Killer Toxins using LC-MS/MS

Malaria is not caused by a virus or bacteria but is spread by parasites known as Plasmodium. These parasites continue to evolve and some of them have developed a resistance to antimalarial medicine, posing a threat to global health programs striving to control and eliminate the disease.

As drug resistance looms large, researchers sometimes turn to natural means to fight certain diseases. Using LC-MS/MS and gel filtration chromatography, the research team at the University of Camerino recently analyzed a certain type of yeast, specifically WaF17.12, extracted from a malaria mosquito. The yeast was found to excrete protein killer toxins which the researchers investigated to determine their effect on Plasmodium berghei, a specie of Plasmodium.

As part of their research, the team at the University of Camerino isolated the various proteins behind the killer toxins which were then analyzed by LC-MS/MS. Findings showed that killer toxins affect the development of the parasite. The research team conclude that, given the impact killer toxins have on the Plasmodium berghei parasite, identifying and analyzing such proteins could open doors to new methods of controlling malaria.

Using a Nitrogen Gas Generator for LC-MS/MS

A number of laboratories across the globe using LC-MS/MS for their analysis are now switching to an on-site nitrogen generator for their nitrogen gas supply. Offering a safe and convenient alternative to bulk nitrogen gas storage in pressurized cylinders, with a nitrogen generator a lab can have nitrogen gas available 24/7 for LC-MS/MS applications, eliminating disruption to sample testing and analysis.
