E.coli strain FB810

[Frank O. Fackelmayer]

Hi all,
I´ve just got an E.coli strain from a friend that may be helpful for
protein expression. It is called "FB810" and the little information I
got is that it is a derivative of BL21(DE3) with a TN10 transposon. Does
anyone know this strain and can give some more detailed information
(exact genotype, constructor, references)?
The obvious sources for information on such material (MedLine, ATCC,
various collections of microorganisms) were not helpful.
