What has been done with Biobricks
Pairwise assembly:
QPI digestions successful with modified protocol:
Pl + QPILac
QPIl + YFP
QPI434 + YFP
Completed first two rounds and started third round of ligations to build
QPIs from scratch
Performing ligations in duplicate to decrease chances of setbacks
Sequenced successful ts (mut265) mutations in LacI
Have sent LacI ts (mut241) and both QPILacI(ts) mutants (m241 and
m265) for sequencing
Outsourced 2 different ts, ind- versions of lcI. (“mJP3” based on
Japanese patent Genbank #E07700, and “m8572” based on cI857
sequence found in HENDRIX Lambda II book).

Summary: What we have done
CollinsMod: (?)
BioBricks:
Pairwise assembly
mCherry + T
RBS + 434
RBS + lcI
RBS + mCherry-Terminator
RBS + Venus-Terminator
QPI digest problem solved; ligations still in testing
Mutations and Sequencing
We have a sequenced Bb-LacI m265
We are sequencing LacI m241 and QPI-lacI m241 and m265
Introducing mJP3 and m8572 into Lambda cI and QPI-Lambda

More Pairwise Assembly
First Round
PlacI(hyb) + RBS-lCI
Pl + RBS-434
RBS + LacIts(265)
All promoters + mCherry
All promoters + Venus
Second Round
Terminator + P434-mCherry
Terminator + P434-Venus
Terminator + Pl -mCherry
Terminator + Pl -Venus
Sequence cI857 mutations
QPIl + mCherry
QPI434 + mCherry
Pl + QPIlacI
Pl-QPIlacI + QPIl-mCherry
Pl-QPIlacI + mCherry
PlacI + QPIl-mCherry
Pl + QPI434-mCherry
Test microscopy with Promoter-Reporter constructs
Are mCherry-expressing colonies red enough?
