Protease inhibitors cocktail for mammalian cells is widely used in biological research to prevent protein degradation during cell lysis and protein extraction. It helps maintain the integrity of proteins by inhibiting a broad spectrum of proteases, ensuring accurate analysis in experiments such as Western blotting, immunoprecipitation, and protein purification. This cocktail is essential in studying protein function, interactions, and post-translational modifications, as it preserves the native state of proteins. It is particularly valuable in handling sensitive samples where protease activity could compromise results. Researchers often use it in combination with other inhibitors to achieve optimal protection against protein degradation.
