Dear all,

sorry for this off topic question. I am producing the ectodomain of a
human receptor in HEK293T cells by transient expression. The expression
levels are quite low. The protein contains a high number of disulfide
bridges. It has been reported that overexpression of protein disulfide
isomerase can enhance the secretion of proteins with a high disulfide
content. I would like to test the effect of PDI by cotransfecting a
PDI-encoding vector with my expression plasmid. I wonder if anybody has
some experience with PDI-overexpression and if anybody could provide me
an mammalian expression construct for PDI?

Any suggestions are appreciated,
