Effective removal of albumin from serum.

The protein constituents of serum can range from grams to picograms per liter, making it technically difficult to achieve in-depth proteomic analysis. Removal of highly abundant proteins, such as albumin, coupled to powerful protein separation methods is required for increased sample load, thus facilitating detection and identification of low-abundant proteins. We report here a chemical-based extraction method for the effective and specific removal of albumin from serum.
