Antibody:	Anti-Cytotactin
Detection system:	Secondary antibody coupled to fluorescein
Assay notes:	The fixative was 2.5% paraformaldehyde. The tissue was flattened and cut using a freezing microtome.

TS28: barrel cortex	Present	Non-Uniform	4A	Expression was detected in the barrel walls but was present at very low levels in the barrel hollows.

TS27: barrel cortex	Present	Non-Uniform	5A	Expression was detected in the walls of the developing barrels. Diffuse staining was seen in the barrel hollows. The differential ratio of expression between the barrel walls and hollows appears to be less than at P7.
