Looking for positive control plasmids on LexA Two-Hybrid Assay

[Antonio]

Dear people,
I wonder if someone have the following plasmids:

pLexA-53
pB42AD-T
pLexA-Lam

They are from Clontech, and are used within the Matchmaker LexA 
Two-Hybrid System. I asked for them but they are not commercially 
available any more. Could anybody send me a sample (costs will be on me, 
of course)?

Thank you in advance,

Antonio
