Scan protocol
Hybridised microarrays were scanned on a GenePix 4000B microarray scanner and the resulting images were analysed with GenePix 5 array analysis software.
Description
Sample details: rostral or caudal thirds of E11.5 MF1 neocortex where pooled from three embryos. RNA was extracted by the Invitrogen Trizol Protocol, Ref: Chomczynski, P. and Sacchi, N. (1987) Analytical Biochemistry 162, 156.
Data processing
log ratios were lowess normalised, and filted to exclude (1) spots flagged as bad and (2) spots where 55% of the foreground pixels in either channel where less intense than the (background intensity + 1SD)
