Proteins of rat serum: II. Influence of some biological parameters of the two-dimensional electrophoresis pattern

This report complements the database already detailed for serum proteins of healthy adult male rats (P. Haynes et al., Electrophoresis 1998, 19, 1484-1492). The influence on the two-dimensional electrophoresis (2-DE) pattern of certain physiological conditions (sex, age) was studied as well as of changes in thyroid metabolism. We have extended the information about the major components of rat serum by identifying the proteins typical for the response to acute inflammation. Analyzing 27 spots, six proteins not found in control sera could be recognized; migration at overlapping or close positions with five already characterized proteins was observed for some.
