Example Isolation of Asialofetuin from a protein mixture Sample: Protein mixture consisting of Protein Standard II (1 µl, #207234) and Asioalofetuin (AF, 1 µg) Beads: <strong>MB</strong>-<strong>LAC</strong> <strong>AIA</strong> Target: MTP AnchorChip 600/384 Matrix: 2,5-DHAP MALDI mode: Linear Asiaolofetuin (43.2 kDa) was successfully isolated by <strong>MB</strong>-<strong>LAC</strong> <strong>AIA</strong> beads from a protein mixture consisting of BSA (66.4 kDa), Protein A (44.5 kDa) Trypsinogen (23.9 kDa) and Asialofetuin (43.2 kDa). Only Asialofetuin was detected in the eluate and no residual Asiaolfetuin was detected in the supernatant. Page 16 of 19
