A team from the University of Calgary and the National Research Council Plant Biotechnology Institute has been studying the alkaloid metabolism process that commonly takes place in opium poppy cell cultures, using liquid chromatography and mass spectrometry (LC-MS).
The team published their findings in BMC Plant Biology, an open-access publication, where they explained how using LC-MS enabled them to analyze protein extracts within cell cultures that had been treated using a fungal elicitor.
The poppy flower, from which several different pharmacological solutions like codeine and morphine are commonly derived from, contains 1,004 different proteins, identified and analyzed using LC-MS.
The scientists were able to compile an opium poppy-specific expressed sequence tag database, allowing them to greatly improve their identification of the different proteins.
Getting accurate IR spectra on monolayer of molecules
April 18th 2024Creating uniform and repeatable monolayers is incredibly important for both scientific pursuits as well as the manufacturing of products in semiconductor, biotechnology, and. other industries. However, measuring monolayers and functionalized surfaces directly is. difficult, and many rely on a variety of characterization techniques that when used together can provide some degree of confidence. By combining non-contact atomic force microscopy (AFM) and IR spectroscopy, IR PiFM provides sensitive and accurate analysis of sub-monolayer of molecules without the concern of tip-sample cross contamination. Dr. Sung Park, Molecular Vista, joined Spectroscopy to provide insights on how IR PiFM can acquire IR signature of monolayer films due to its unique implementation.
