Universal Protein Precipitating Reagent: Protein soluons as dilute as 1ng/ml can be quantavely concentrated into a small volume through the Universal Protein Precipitaon Reagent. Protein precipitaon is not affected by the presence of detergents, chaotropics, sucrose, reducing agents, or other common laboratory agents. The final protein precipitate is re‐suspended in a small volume of buffer and the recovery is generally 100%. The Reagent is suitable for concentrang proteins for downstream applicaons such as gel electrophoresis and protein purificaon. The reagent is not suitable for proteins whose acvity must be maintained for further research. The Reagent can perform 100 preparaons and concentrate 10ml total of protein sample soluon.
