| Two days after transfection had been initiated, cells were passaged onto coverslips. |
| These cells had been passaged through 14 passages and were grown to confluence in 35 mm culture dishes. |
| There Banjo sidled, yawed, and passaged, fretting to be after the brown. |
| The forebrain and spinal cord cultures expanded the fastest and could be passaged every 7-14 days. |
| Such vaccines were made in the skin of calves and sheep, and seeds and stocks were passaged in tissues of calves, sheep, and rabbits. |
| Deletions of gene 1.3 were introduced into the preadapted virus, and the recombinant virus was then passaged to allow fitness recovery. |
