In older posts here, people have suggested MAP2 as a good dendrite marker, though not clear if that is relevant for your mouse hippocampus neurons. If you want to explore some sources for anti-MAP2, we list quite a few:

Hope this is of use.

Hey Russell - unfortunately while MAP2 is a dendritic marker, it marks excitatory as well as inhibitory neurons (e.g. this paper: http://www.ncbi.nlm.nih.gov/pubmed/12834896).  I'm looking specifically for a marker of the dendrites of GABAergic, inhibitory neurons.

Hi Kaitlin,

I' m working for the antibody producing company Synaptic Systems. Maybe a co-staining from MAP2 and Parvalbumin as Marker for GABAergic interneurons could help. Also Calbindin and Calretinin as Markers could be interesting. I can offer you samples of antibodies against this targets, please contact me at [email protected]. Here are the links to the web-sites;

Hi Kaitlin,

I agree with Carsten Schmidt. The Ca-binding proteins like Parv, Calbindin or Calretinin show  nice images with dentrites. But most of the Ca-Binding proteins are subpopulations. That means not all GABAergic interneurons are Parv or Calbindin or Calretin positiv. I use the antibodies against  Ca-binding protaeins from swant.com for many years with good results.
