Zymed Labs (415-871-4494 and 800-874-4494 in US) cells rabbit
polyclonals. They advertize them as "suitable for 
immunohistochemistry". We tried them for Westerns with whole brain
extracts and were never convinced the the signal is specific.
This simply could be due to low abundance of chtomogranin A.
You might have better luck with intestine.
