SDS 8-18% PAGE of reduced samples of GMP human pentraxins.
a, GMP human SAP. Lane 1, molecular weight marker proteins: 94 kD,
67 kD, 43 kD, 30 kD,
20.1 kD, 14.4 kD; lane 2, SAP 25 μg; lane 3, SAP 50 μg; lane 4, SAP 75 μg; lane 5, SAP 100 μg. b, GMP human CRP. Lane 1,
marker proteins; lane 2, CRP 60 μg; lane 3, CRP 30 μg. The trace higher molecular weight impurities identified by proteomic analysis
as IgM μ chain and plasmin/plasminogen respectively are seen in lanes 2 and 3. c, GMP
human CRP. Lane 1, marker proteins; lane 2, CRP 5 μg.
