Primers used.

1sequences are indicated 5′ to 3′.2the relevant location of each primer is indicated, along with how the primer was used. Primers to chromosomal regions are usually near the site of integration of ICEBs1. The position, 5′ or 3′, in the indicated gene is relative to the direction of transcription of that gene, 5′ indicating extension in the same and 3′ indicating extension in the opposite direction as transcription. Left and right ends of ICEBs1 are as in Figure 1.
