Figure 2From: Comparative secretomic and N-glycoproteomic profiling in human MCF-7 breast cancer and HMEpC normal epithelial cell lines using a gel-based strategyHaptoglobin glycoforms. Panel A and panel B demonstrates the cropped image of β chain of haptoglobin glycoforms obtained from 2-DE total growth medium profile and N-glycoproteins profiles of MCF-7, respectively. It is a 45 kDa homotetramer with pI ranged from 5.5 to 6.5.Back to article page
