Mammoth Collagen Sequenced Using Mass Spectrometry
Scientists use an ultra-high resolution mass spectrometer to extract proteins from the bones of a 600,000-year-old mammoth.
Scientists from the University of York (York, United Kingdom) and the University of Manchester (Manchester, United Kingom) have used an ultra-high resolution mass spectrometer to extract proteins from the bones of a 600,000-year-old mammoth. With these proteins, the team was able to create a nearly complete collagen sequence for the skeleton known as the West Runton Elephant.
In a statement issued by the University of York, Mike Buckley, PhD, one of three co-researchers, says that the protein extracted “is an ideal target for obtaining long lost genetic information.” Although there have been controversial reports of peptides discovered in dinosaur fossils, the team argues that the collagen sequence from the West Runton Elephant is the oldest protein ever sequenced.
The team conducted their research at the Centre for Excellence in Mass Spectrometry at the University of York, and applied their findings to an overall study of mammoths and mastadons published in the April 2011 issue of Geochimica et Cosmochimica Acta.
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.
Deep Level Transient Spectroscopy Reveals Influence of Defects on 2D Semiconductor Devices
April 25th 2024A recent study used deep level transient spectroscopy to investigate the electrical response of defect filling and emission in monolayer metal-organic chemical vapor deposition (MOCVD)-grown materials deposited on complementary metal-oxide-semiconductor (CMOS)-compatible substrates.
Single Cell and Microplastic Analysis by ICP-MS with Automated Micro-Flow Sample Introduction
April 25th 2024Single cell ICP-MS (scICP-MS) is increasingly seen as a powerful and fast tool for the measurement of elements in individual cells, mainly due to the high sensitivity and selectivity of ICP-MS. Analysis is performed in the same way as single nanoparticle (spICP-MS) analysis, which has become a well-established technique for the analysis of nanoparticles and particles.
