Application

EPPS has been used:
  • to verify the effect of pH variation on the proteolytic activity of the posterior midgut (PMG) contents and anterior midgut (AMG) tissue homogenate
  • to prepare a destaining buffer to destain intensely stained gel pieces
  • to prepare digestion buffer for in-gel enzymatic digestion
  • to reconstitute the digested peptides for the processing of brain-derived extracellular vesicle (EV) proteins and 16-plex isobaric tandem mass tag (TMT) peptide labeling

Recombinant monoclonal antibodies are predominantly produced in mammalian cell culture bioprocesses. Post-translational modifications affect the micro-heterogeneity of the product and thereby influence important quality attributes, such as stability, solubility, pharmacodynamics and pharmacokinetics.

Mammalian cells reorganize their proteomes in response to nutrient stress through translational suppression and degradative mechanisms using the proteasome and autophagy systems1,2. Ribosomes are central targets of this response, as they are responsible for translation and subject to lysosomal turnover
