The study of biofluids, cell, bacteria, yeast, and tissue lysates has delivered vital information regarding their biochemical composition. These biological samples comprise a rich, complex list of lipids, proteins, small organic molecules, ions, and, depending on the sample, exogenous molecules (i.e. drugs). Several small organic molecules can also be found free and/or bound to other macromolecules. These macromolecules (lipoproteins, proteins, enzymes) interfere or degrade low molecular-weight metabolites. Therefore, sample deproteinization is often required. Chemical deproteinization procedure such as Trichloroacetic acid (TCA) is one of the most utilized methods to accomplish sample deproteinization. BioVision's Deproteinizing Sample Pre
