Protein Precipitation - an overview | ScienceDirect Topics
A fast and simple method of sample preparation is protein precipitation, also referred to as ‘dilute and shoot.’ This nonselective technique involves adding a water-miscible organic solvent (e.g., acetonitrile) or inorganic acid (e.g., trichloroacetic acid, 10%) to the biological matrix (usually in a 3:1 or 4:1 ratio, v/v), centrifuging or
Ultrasensitive CRISPR-based diagnostic for field
Sep 15, 2020· Nucleases require metal ions as cofactors and therefore chelating agents inhibit their activity. S-PREP is a simplified sample preparation method where sample is diluted 1:3 (5 μL into 15 μL of S-PREP buffer) followed by heating to 95 °C for 10 min. We eliminated the false-positive signals of serum samples using S-PREP (Fig. 4 C and D). We
