Post-translational transfer into ER?

Is there a way to reliably load peptides into the lumen of the ER, 
post-translationally?  What we'd like to do is load cells (by osmotic 
loading) with a peptide, and compare effects when it's in the cytosol and 
when it's in the ER.  I have a vague memory of some bacterial toxin that 
targets ER, but it is, alas, too vague to actually be useful.
