GAD 65/67 antibody

Hi guys,
I have been trying to get the Chemicon AB1511 Rabbit anti-gad65/67 antibody with a AP132R gaot anti-rabbit secondary to work.
 
I have no success in doing so. I was wondering if any of you are using the same primary antibody and if yes, can you please give me the protocol for the same.
 
Thanks,
Vilay
