DNA-Vacc...Why PBS, not TE

Why should anyone use PBS to solute the plasmid before injection into a mouse and not TE-buffer?
Thanks in advance,

Dear Chris,

IMHO, cells do not like Tris nor EDTA.
THese things are good for storing your DNA, but PBS is more agreable
for cells, I suppose.
I know of a few enzymes that can be inhibited by Tris (e.g. sucrase).
EDTA will mess up the Calcium metabolism, almost for sure.
Also, TE is usually used for DNA at pH=8 to 8.5, which is too high.
PBS at about pH 7.something is closer to what cells like.

Just a thought......

Hope this is useful info.   :-)
