Figure 2.
High molecular weight proteins of >240 kDa are glycoprotein ligands of rBC2LCN in human iPS cells and ES cells. One microgram of hydrophilic fractions of somatic cells, iPS cells, and ES cells was run on 5%–20% acrylamide gel under reducing conditions, electroblotted onto polyvinylidene difluoride membrane, and stained with 1 μg/ml of HRP-conjugated rBC2LCN (top panel). Silver staining was also performed (bottom panel). Abbreviations: ES, embryonic stem; HRP, horseradish peroxidase; iPS, induced pluripotent stem; MEF, mouse embryonic fibroblasts.
