Using LC-MS to Study Protein Expression in Crop Development
July 10th 2012As the need for improvements in the yield, insect resistance, and abiotic stress tolerance of crop plants continues to increase, Gia C. Fazio and colleagues Wayne Skinner, Zina Dahmani, Yingzhi Lu, and Jean C. Kridl have collaborated on a paper that describes the use of liquid chromatography–mass spectrometry (LC–MS) to quantify the expression of levels of a transgenic protein, barley alanine aminotransferase, across multiple rice lines.
Shimadzu supports drug discovery
July 6th 2012Shimadzu has announced that, in partnership with the Sugiyama Laboratory within the RIKEN Innovation Centre of the RIKEN Research Cluster for Innovation, it has started research on quantitative analysis methods using LC–MS–MS to support drug discovery using microdosing.
Can You Meet the Technical Requirements of Annex 11?
July 1st 2012The new version of EU GMP Annex 11 has been effective for about a year. There are new technical requirements in the Annex – do your laboratory computerized systems comply with them all? In this column we look at the impact of these new regulatory requirements for Good Manufacturing Practice laboratories.
Direct Insertion Probe – Mass Spectrometry in the Characterization of Opportunity Crudes
July 1st 2012DIP–MS is a fast and easy tool that can identify classes of compounds in opportunity crudes (heavy and ultraheavy crude oils, asphaltenes, and tar sands) in the field, without prior separation or treatment. It may enable fast screening of real samples to make a rough evaluation of the potential of reservoirs and oil fields.
Toward Quantitative Imaging Mass Spectrometry
The main limitations of quantification using MALDI imaging are discussed and the different approaches used for quantitative measurement in MSI are evaluated.
