Abstract

Serum and plasma are the major sources of human material for clinical molecular diagnostics and drug discovery. However, due to the high abundance of some proteins, of which serum albumin (SA) is most prominent, lower-abundance proteins often remain undetectable in proteomic analysis of these body fluids. We have used hexadecanedionic acid (HDA) immobilized to Sepharose 4B to develop an affinity resin that is effective in the removal of SA from plasma. Two-dimensional gel analysis of the SA-depleted samples shows a significant enhancement of the low-abundance proteins and highly specific capture of serum albumin. The HDA resin shows better performance in terms of specificity than dye-based resins.
