Abstract:
We characterized the two-dimensional electrophoretic patterns of fibrinogen chains alpha, beta, and gamma from the plasma of six animal species -Bos taurus, Canis familiaris, Equus caballus, Felis catus, Gallus domesticus and Sus scrofa. Comparing the spots resolved from serum and plasma samples, or exploiting the cross-reactivity of animal fibrinogen with an antiserum raised against the human protein could detect only some of the fibrinogen chains. Conversely, the analysis of the precipitate obtained by heating plasma for some minutes at 56 degrees C was adequate for the recognition of all fibrinogen chains in all samples. Physicochemical properties of the homologous proteins were found to extensively vary across species, with complete separation among the mapping areas for alpha, beta and gamma chains and maximal heterogeneity among beta chains.

Two-dimensional Gel Electrophoresis
The first dimension separation uses the isoelectric focusing or IEF technique performed on immobilized pH gradient (IPG) strips that separate proteins according to their isoelectric points.

SDS-PAGE
A variation of gel electrophoresis, termed polyacrylamide gel electrophoresis (PAGE), is commonly used for separating proteins according to their molecular size by passing them through a polyacrylamide gel. Because of the varying charges associated with amino acid side chains, PAGE can be used to separate intact proteins...
