When we have performed antibody stainings on fixed Drosophila embryos we have noticed that there is
significant variation in intensity of staining for embryos of the same developmental stage.
The embryos were all fixed together, in the same fix (i.e not a staining of multiple fixed embryos
pooled together), and fixed using either paraformaldehyde or formaldehyde. This occurs with various
As well as variation between embryos we sometimes see variation in intensity of staining within the
If anyone has any ideas on why such variation is occurring and what we can do to reduce it then your
advice would be appreciated.
