General description

The study of biological fluids, 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. 

Suitability

Suitable for deproteinizing biological fluids (serum, plasma, whole blood, saliva, urine etc.) and lysates (cell culture, mammalian tissue, yeast, bacteria etc.)

Principle

The Deproteinizing Sample Preparation Kit II offers an excellent alternative when metabolite lability affects the accurate detection and estimation of small molecule concentrations and when organic solvents or ultrafiltration cannot be used. TCA precipitates proteins by lowering the sample pH drastically. After removal of precipitated proteins, the pH of the sample is neutralized with neutralization buffer that is provided in the kit.
