Aminoacidcomposition

There has been a recent revival of interest in the use of AA composition for the identification of proteins from 2-D gels. This technique uses the idiosyncratic AA composition profile of a protein in order to identify it by comparison with theoretical AA compositions of proteins in databases. For identification of proteins from 2-D gels, we match the AA composition in conjunction with estimated protein pI and Mw. Pro......阅读全文
