In this study, we profiled the placental proteome of IUGR twins and normal cotwins from 6 monochorionic twin pairs with selective intrauterine growth restriction (sIUGR).
The total proteins from tumor tissues were seperated by tricine SDS-PAGE and stained with silver. The gel band with about 7kD molecular weight related to RBRP peptide was identified by LC-MS/MS.
