Hi, first of all I wish you all a very Happy and Healthy New Year!

Has anybody experiences with the in-culture-labelling of S. aureus with 
CFDA-SE? Why do I want to do that? Well, for internalisation assays I 
would like to use bacteria which are not too much handled before the 
co-cultivation with eukaryotic cells starts.
I tried this way of labelling (24h culture)once, but the cells showed a 
very low fluorescence. And I don´t know, if it is because I used e.g. 
not enough CFDA-SE or if it is generally impossible. Therefore I would 
be happy to hear from your experiences.
