<p>Since we were having difficulties with ampicillin for use with pSB1A3, we started this week by attempting to switch our destination vector to pSB1K3. Unfortunately, none of the ligation transformations showed any growth, so we quickly abandoned this idea and stuck with streaking instead. We received sequencing results that showed that our 'no signal peptide' control construct had successfully been cloned into pSB1A3. Efforts to transform this part into E. coli BL21 (DE3) began this week. The sequencing reaction for our Golden Gate-assembled construct sent last week unfortunately failed. We PCR-amplified all of our GBlocks from IDT to create DNA stockpiles for performing Golden Gate, and then repeated all of the Golden Gate reactions again. In addition, we repeated our colony PCR screening for all of the colonies that are white in appearance, indicating that the assembled construct has replaced the RFP flipper in the destination vector. Constructs containing the signal peptides from DsbA, MalE, OmpA, PhoA, and TorA showed positive cPCR results and were sent for sequencing. The construct containing the 'Tat' signal peptide was cPCR-confirmed later in the week and will be sent for sequencing next week. We also began the process of transforming all of the constructs containing signal peptides into E. coli BL21 (DE3). Members of our subgroup also took part in education and outreach work this week by beginning to plan an informational 'Bacteria Night' event.</p>
