    Notes: An updated human heart protein two-dimensional electrophoresis (2-DE) database is presented. The database, which contains some 1388 protein spots characterised in terms of Mr and pI, has been analysed further by Western immunoblotting and protein sequencing. From a total of 103 protein spots analysed, 49 have been identified by immunoblotting and 32 have been identified by protein sequencing. A further six proteins have tentatively been assigned by comparison with the human heart 2-DE protein database of Jungblut et al. (Electrophoresis) 1994, 15, 685-607). This database is being used in studies of alterations in protein expression in the diseased and transplanted human heart.

    Notes: Protein purification and characterisation have been age-old problems for the biochemist. A new era has arisen with the advent of one- and two-dimensional gel electrophoresis and high sensitivity automated protein microsequencing. These two tools along with electroblotting have made it possible to separate and analyse complex protein mixtures. We studied six different membranes compatible with Edman degradation chemistry to determine their efficiencies at binding proteins electroblotted from one-dimensional sodium dodecyl sulphate-polyacrylamide gel electrophoresis. Their overall blotting-sequencing properties were also evaluated. We found that the polyvinylidene difluoride-based membranes out-performed the glass-based and polypropylene-based membranes under our selec ted experimental conditions. The problems associated with electroblotting and microsequencing are discussed.

    Notes: This communication briefly describes how a human heart two-dimensional electrophoresis (2-DE) protein database is being established in our laboratory. The database contains more than 1500 polypeptides and approximately fifty proteins from 2-DE gels of human myocardial tissue have been characterised. Information about the proteins has been compiled including molecular weight (Mr), isoelectric point (pI), sample spot (SSP) number, protein name, partial sequence, and antibody reacting with the protein. The first stage of this project involves the investigation of protein with pIs in the range pH 4-7. Future studies will employ immobilised pH gradient (IPG) gels as the first dimension of the 2-DE to examine basic proteins. The ultimate goal of this project is to establish a global picture of human heart protein expression in both normal and disease conditions.
