The data of SDS-PAGE and MALDI mass spectrometry analysis of the SPC proteins with high molecular masses from three placenta preparations (before and after the SPC treatment with DTT).

*For each value, a mean ± S.E. of three repeats corresponding to three different SPC preparations are used; the errors of any MM determination by MALDI mass spectrometry did not exceed 0.5–1.5%.
**The range of some MM values corresponds to non-glycosylated and several different glycosylated forms of proteins and their complexes with H+, Na+, K+ ions.
***Several proteins were revealed as major ones only in the case of the complexes from the first and third placenta preparations.
§Major proteins are marked in bold.
