19b. SDS-PAGE on PhastSystem, using PhastGel 4–15 with silver staining. 5 with 30% isopropanol The sample must have the same concentration of ammonium sulphate as the binding buffer. 8 M. Stir slowly and continuously. 45 µm filter immediately before applying it to the column. 8 M ammonium sulphate. 0 M. To avoid precipitation of IgM, it is important to add the ammonium sulphate slowly. An increased concentration of ammonium sulphate will cause more IgG to bind, which might be a problem if serum has been added to the cell culture medium.

HiTrap columns can be used with a syringe, a peristaltic pump or connected to a liquid chromatography system, such as ÄKTAprime. Reuse of HiTrap lgM Purification HP depends on the nature of the sample and should only be considered when processing identical samples to avoid cross-contamination. 39 Media characteristics HiTrap IgM Purification HP Ligand and density pH stability* 2-mercaptopyridine 2 mg/ml Long term 3–11 Short term 2–13 Mean particle size 34 µm *Long term refers to the pH interval over which the medium is stable over a long period of time without adverse effects on its subsequent chromatographic performance.
