goal: Obtaining pLASs with 3-a assembly
 
Extra amounts of dspB, dspB+HIS, aiiA, aiiA+HIS,aiiA+HIS, pLAS, RBS, double terminator, pSB2k3, pSB1C3 and pSB1A3 were miniprepped to be used for the assembly
 
1 ug of aiiA, dspB, dspB+HIS and aiiA+HIS with XbaI and PstI and 1 ug of RBS was cut with EcoRI and SpeI
 
These were eventually ligated for 3 hours into pSB2K3 and transformed into E. coli NEB cells

After growing them for 1 day, colony PCR was done on the correct clones, these were inoculated for plasmid extraction
 
Then A1’, A4’ was digested with XbaI and PstI. A2’ and A3’ was cut with EcoRI and SpeI. Then ligated

After doing growing analyzing and miniprepping the correct clones, A1” and A3”was cut with EcoRI and SpeI. A2” and A4” was cut with XbaI and PstI and ligated afterwards

Then the whole transformation protocol occurred and the correct clones were confirmed with sequencing.
