Hi. If you don't find the conjugated antibody commercially available you can always try to label your samples with CD11d and then use a second label (ie FITC) to detect the signal.

BD should be able to inform you about the possibilities they offer this

I found this list of unrated antibodies from Lifespan biosciences http://goo.gl/Ha47aB.

Hope that's a good start for your experiment.

Have you found something that works? I'm looking for the same.
