Instructions for use

For acting, the Giemsa should always be used diluted. Depending on the dilution, the staining will be rapid or slow.

FOR INFORMATION:

  • Rapid staining: 10% dilution with staining time of 8-10 minutes
  • Slow staining : 3% dilution with staining time of 45-60 minutes

These times vary according to the quality of the Giemsa and you need to make some tests to find out the best protocol.

To guarantee the staining quality, the dilution should be performed extemporaneously with buffered water at pH 7.2.

Please consult the “Updated laboratory procedures, 2022” available online via the Laboratory working Group sharepoint page: Laboratory Procedures and Resources.
