Next Generation Synthesis

In this week, we tried to change the color-generating chromophore of the purple Acropora millepora chromoprotein (amilCP) to a variety of orange, pink, and blue mutants. These divergently-colored genetic variants of amilCP were described by Liljeruhm et al in 2018.

1. Digest the pUC19 plasmid with the restriction enzyme PvuII to generate the linear blunt-ended backbone fragment.



                  Green: pUC19 plasmid  
                  Right: Buffer CutSmart  
                  White: DNase/RNase-Free Water 
                  NEB PvuII-HF(restriction enzyme)     
                  

Incubate reactions at 37C for 15 minutes in thermocycler


2. Prepare PCR fragments for the gene assembly of amilCP mutants.
