Liquid chromatography-mass spectrometry (LC-MS) and electrophoresis are both common approaches in the field of skeletal muscle proteomics, notes a researcher.
In a status report on the discipline published in Skeletal Muscle, Kay Ohlendieck from the Muscle Biology Laboratory at the National University of Ireland Department of Biology lists electrophoresis and LC-MS among the main techniques currently used.
This typically means large-scale separation of the sample, followed by high-throughput identification of proteins present.
According to the author, there are inherent difficulties in skeletal muscle analysis that mean many forms of assessing the data are unsuitable for proteomics purposes.
"Skeletal muscle fibres represent one of the most abundant cell types in mammals," readers are told.
Very high molecular masses in the fibres' membrane-associated proteins and the complexity of the structures in the tissue make conventional
biochemistry more difficult, the article adds.
The open-access periodical Skeletal Muscle reports findings relating to the development, regulation and metabolism of muscles in the skeleton, along with issues like degeneration and dystrophy.
