| 摘要 |
The invention relates to a high gradient magnet separation device for the separation or purification of magnetic or magnetically labeled biological material, comprising a magnet, a separating column, and a ferromagnetic matrix that can be arranged in an interior chamber of the separating column, and a storage container containing a buffer solution for the equilibration of the separating column and/or for the suspension of the biological material, wherein during operation a magnetic field created by the magnet creates a high gradient magnetic filed in the matrix and buffer solution can flow from the storage container through the separating column. For this purpose, the buffer solution comprises a base solution and macromolecules that can saturate nonspecific binding sites of the matrix. |
