Description

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
