I'm interested in using a bromo-DNA product as a probe to study
transfection mechanisms in cells genetically deficient in lysosomal
function or in the presence of lysosomal protease inhibitors.
A short technical report recently publisheded in BIOTECHNIQUES (21:82-86
July 1996) <<Application of 5-Bromo-2'Deoxyuridine as a Label for In Situ
Hybridization in Chromosome Microdissection and . . . >> gives no
references in the abstract when mentioning, "An especially useful
application is that it [BrdU] may be incorporated into probe DNA while . .
. plasmids in bacteria are growing in the presence of BrdU."
Does anyone have protocol references for incorporating BrdU into probe
plasmid DNA grown in bacteria, or perhaps, a supply of E. coli thymine
auxotrophs lying around?
Also, I purchased some BrdUTP from SIGMA (for PCR incorporation
of BrdU), and would like to have an alternate, more reliable source.
Any more known suppliers of bromodeoxyuridines?
Thanks for your time.
