| Abstract: | A two-dimensional map of human heart left ventricular proteins for 213 polypeptide fractions has been constructed. A quantitative analysis of variability of the fraction position at 60 selected spots with the use of a CVIT computer system revealed a high reproducibility of the material distribution on electrophoregrams. Differences were found in the protein composition of eight heart muscle atrial and ventricular polypeptide fractions. Left ventricular proteins were shown to be represented by six electrophoretical variants. The methodological peculiarities of construction at the two-dimensional map of heart muscle proteins are discussed. |
