Summary of differential display PCR results
| Total number of clones amplified | 82 |
| Number higher in caudal neocortex | 37 |
| Number higher in rostral neocortex | 45 |
| Identity | Number of genes identified |
|---|---|
| Unknown* | 58 |
| Secreted and transmembrane proteins | 5 |
| Transcription factors | 6 |
| Intracellular enzymes | 6 |
| Nuclear proteins | 7 |
The numbers indicated are from the primary screen; i.e., of the 82 gene fragments scored as differentially expressed, 37 are preferentially amplified in caudal neocortex.
↵* The majority of the unknowns are EST fragments.
