Free secretory component

Does anybody know where I can get some purified human free secretory
component from?  I'm trying to set up an ELISA to measure FSC levels in
human saliva; I can find the antibodies but I can't find a purified
source of FSC.  Any help would be appreciated.

Also, does anybody know of a source of reference saliva?  I'm concerned
about matrix effects of the saliva on the assay and some reference
saliva would be useful.

Thanks, Matt
