Radiolabeled 26Al inhalation studies were performed using tagged gamma aluminum oxide. The results showed that the material acted as an insoluble dust. about 45% was cleared from the lung after one day, with slow mechanical clearance from the lungs of the balance. After 72 days, only 0.2% of the alumina remained in the lung.
Spin column-based nucleic acid purifiion - Wikipedia
Procedure. The stages of the method are lyse, bind, wash and elute, i.e. lysis of cells, binding of nucleic acid to silica gel merane, washing the nucleic acid bound to the silica gel merane and elution of the nucleic acid. To lyse, the cells of a sample are processed with a lytic procedure, which involves breaking the cell merane and freeing the nucleic acid.
