Isol. of Transcription factors

[Bernhard Schrautemeier]

I am looking for a method for positive selection of (cyano)bacterial
transcription factors expressed in (E. coli) gene libraries to isolate the
corresponding gene.  

Also I heard that it is possible to bind promoter-containing DNA sequences
to certain matrices (e. g. latex; J. Biomater. Sci. Polym. Ed. 5(4),
293-302, 1994; I don´t have access to this journal) and thus to
selectively purify binding proteins, e.g. for use in footprinting.

I would be glad to get some help!
