As an alternative to the production and use of monoclonal antisynapton
emal complex (SC) antibodies to isolate SC genes, we have explored the
use of polyclonal anti-SC antibodies to identify SC genes from a cDNA
expression library. The method proved relatively simple, reliable, an
d fast and has yielded two SC genes, A homologue of one of these genes
from a different species has previously been isolated in another labo
ratory.
