Two-promoter expression vector

[Mendell Rimer]

Hi there!
	I am looking for eucaryotic expression vectors that carry two
promoters for the production of two gene products simultaneously. Does
anybody has one available out there or knows of a commercial or academic
source for it? E-mail to Rimer at leland.stanford.edu  appreciated. Thanks in
advance,
