Biotin+Plasmid

[mp]

Hi every one
I was wondering if  there is any kit out there that uses  biotin for
labeling DNA probes (like PCR products) and using Streptavidin coated
magnetic beads for isolation of the corresponding plasmid from a
library. I know Gibco has the GeneTrapper kit for cDNA, but it has other
components that I do not need, so it makes that kit expensive. I would
apprecite if you know any supplier and give me the address.
