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. The analysis of the surface charge distribution of

Detection of amyloid-β (Aβ) aggregates contributes to the diagnosis of Alzheimer disease (AD). Plasma Aβ is deemed a less invasive and more accessible hallmark of AD, as Aβ can penetrate blood-brain barriers. However, correlations between biofluidic Aβ concentrations and AD

In neurodegenerative diseases, extracellular vesicles (EVs) transfer pathogenic molecules and are consequently involved in disease progression. We have investigated the proteomic profiles of EVs that were isolated from four different human-induced pluripotent stem cell-derived neural cell types (excitatory neurons, astrocytes
