| Each dilution was kept for amplification and the amount of DNA present in each dilution was estimated spectrophotometrically. |
| Functional residual capacity was measured by helium dilution over 7 min of rebreathing in closed circuit. |
| From this lysate, a dilution was prepared and used as a source of DNA in amplification reaction. |
| Africanized queens are free to mate with European drones, and perhaps this has resulted in a dilution of the Africanized gene pool. |
| Numbers of bacteria were measured using soil dilution plating on soil extract agar media. |
| The old-timers meanwhile resisted dilution of the great franchise enjoyed by the name. |
