Proteomics (e)

datE: 12-03-2024 Status: Under DEVELOPMENT

 

Proteomics concerns experiments on all protein molecules in a sample, including information about so-called post-translational modifications. This may involve experiments that attempt to determine which proteins are found (identification) and in what concentration proteins are found (quantification). In addition, position-specific imaging techniques are also possible.
