MetabolomicsCharacterization of Whole Blood EVs Using PRotein Organic Solvent PRecipitation

Blood plays a vital role in diagnostic medicine by providing essential information for assessing health and diagnosing various conditions. Routine blood tests can reveal important biomarkers that support early diagnosis and timely intervention. Recently, extracellular vesicles (EVs) have emerged ...

ProteomicsSolvent Precipitation SP3 (SP4) enhances recovery for proteomics sample preparation without magnetic beads
Complete, reproducible extraction of protein material is essential for comprehensive and unbiased proteome analyses. A current gold standard is single-pot, solid-phase-enhanced sample preparation (SP3), in which organic solvent and magnetic beads are used to denature and capture proteins, with subse...

ProteomicsRapiGest Precipitation Depends on Peptide Concentration
The mass spectrometry-compatible surfactant RapiGest promotes the enzymatic digestion of proteins by facilitating their unfolding while retaining enzymatic activity. RapiGest consists of a hydrophilic head and a hydrophobic tail, which can be separated by acid hydrolysis. This allows for removal of ...

ProteomicsIsolation of extracellular vesicles by PROSPR
Here, we report a novel and inexpensive method of rapidly isolating EVs from small volumes of human blood plasma by PRotein Organic Solvent PRecipitation (PROSPR). PROSPR encompasses a rapid three-step protocol to remove soluble proteins from plasma via precipitation in cold acetone, leaving the lip...
