Depositor Comments

Gateway L1L3 entry vector containing the tTA regulator. Promoters can be inserted using PacI and SbfI. Does not contain insulator sequence.

Plasmid was constructed as follows: The pEntr2B entry vector (Invitrogen) was digested with PstI and XhoI to remove the attL2 site.
Oligonucleotides containing SalI-XhoI-Bsu36I-NdeI-PacI-EcoRI-NotI flanking the attL3 sequence on the 5' side
and PstI on the 3' side were ligated in to create an intermediate plasmid carrying attL1 and attL3 sites. A LoxP sequence was introduced at the XhoI site. The tTA and pA sequences were subsequently cloned into the EcoRI/NotI sites by PCR cloning from pUHG15-1 to generate pEntL1L3 tTA-3.
