Dear Lorenzo, I use the goat polyclonal DCX from Santa Cruz and it works very good. I use it in brain slices from perfused mice. Blocking 1 h 3% donkey serum and incubation ON at 4C in 3% donkey serum and 1:100. Good luck!
Like Sara, I also use the goat polyclonal (sc-8066) from Santa Cruz at the same dilutions as mentioned above. I have done o/n and 48h incubations with the primary antibody and find the 48 h incubation to be very good. I use 40um PFA-perfused mouse brain sections on slides.
