Promega sells lambda gt11 cloning kit as well as the strain Y1089.

Where you will read about:
Y1089 (1): 

The strain Y1089 is used primarily for the generation of preparative 
amounts of fusion protein (see
Section VIII). This is possible because of a mutation which enhances the 
frequency of phage
lysogeny (hflA150) and the deltalon mutation which decreases protease 
activity. Like Y1090, this
strain also contains pMC9 (described above). 

Genotype: F´, delta(lacU169), proA+, delta(lon), araD139, strA, hflA150, 
[chr:Tn10(tetr)],
(pMC9).
