Modifications of the expression of plasma proteins can be related to genetic variations, complex combinations of post-translational modifications, alterations directly or indirectly related to diseases, or combinations of these mechanisms. Genetic variants of proteins such as haptoglobin, Gc-globulin, apolipoprotein E, apolipoprotein A-1, transferrin, or alpha-1-antitrypsin can be identified using 2-DE (Anderson and Anderson, 1979 Rosenblum et al, 1983 Tissot et al, 1993b Tissot et al, 2000b). 

Simple systems (with a single defined additive) were produced with each of the following materials. Calf thymus DNA, polymerized, was obtained from Sigma. Protein sources were prepared in-house and subsequently dialyzed into low salt solutions. Human serum albumin and immunoglobulin G (IgG) were plasma-derived. Human immunoglobulin M (IgM) was produced by tissue culture fermentation and purified. A defined complex system consisted of both albumin and IgM together. An undefined complex system was set up with an intermediate material of Cohn plasma fractionation containing alpha-1 antitrypsin (alpha-1), albumin, and other contaminants.
