I need to stain mouse brain sections with c-fos and phospo s6 (which is rabbit). I'm looking for a c-fos ab (mouse) because I don't want to perform a multiple immunolabeling with primary ab originating from the same host species.
If a rat antibody would also be possible then try 226017 from Synaptic Systems we use it with Invitrogens Goat anti-rat A21247 both at 1:1000 with good success
I'm from the company Synaptic Systems, additional to the rat monoclonal c-Fos we also offer 2 new antibodies; recombinatly produced monoclonal guinea pig anti-c-Fos

and recombinatly produced monoclonal chicken c-Fos

If this hosts suit your experimental approach better, I can organize free trial size (=1/5 of catalog format) samples.
