A variation of the usual PCRprotocol needed - (May/19/2001 )

I need to know how to make a variation of the usual PCR protocol that would enable me to amplify entirely new genomic sequenceson both sides of the single known sequence. Any help would be verymuch appreciated.

A few solutions available for your question:1. Commercial kit like Chromosome Walker from ClonTech

2. Amplification of Gene-regulating region with single-sided specificity in PCR cloning protocol from Humana Press

3. Adaptor ligation-based PCR-mediated walkingAnalytic Biochemistry 260, 149-153,1998

Sounds like you are looking for the vectorette kit from Genosys.

You could try Tail PCR, it was developed for finding flanking regions to transposon insertions.
