Low copy BioBrick standard vector with LacI
| Types | DnaRegion |
| Roles | plasmid_vector Plasmid_Backbone |
| Sequences | BBa_K864011_sequence (Version 1) |
Description
pSB4A15Iq is a BioBrick standard vector with low copy pSC101 replication origin (~5 copies per cell) and ampicillin antibiotic resistance marker, especially usable for Lambda Red recombineering in E coli. The backbone sequence is based on pSB3T5, but the E coli His operon terminator BBa_B0053 has been replaced with the late terminator of the Salmonella phage P22.This vector carries a LacIq cassette on the backbone for tight repression of any lac promoter cloned into the cloning site.
Notes
The resistance cassette is terminated by a Lux bidirectional terminator. Adjacent to this terminator there is a designed primer binding site to where the forward primer for lambda red can be designed to bind to no matter what the insert in the cloning site is or what the resistance is.The resistance cassette is flanked by SalI and SacI restriction sites for easy switching of resistance in the backbone.
