Digest pUCmini-iCAP-PHP.B plasmidaddgeneCatalog #103002 with MscI - 1,250 unitsNew England BiolabsCatalog #R0534L and AgeI - 1,500 unitsNew England BiolabsCatalog #R0552L
Design 100 bp primers for the desired plasmid variant that cover the insertion region with ~20 bp overlap of the backbone
To synthesize the double-stranded DNA fragment, anneal the primers by PCR with 20 cycles of 98 °C for00:00:10, 60 °C for 00:00:30 and 72 °C for 00:00:10 using Q5 Hot Start High-Fidelity 2X Master Mix - 500 rxnsNew England BiolabsCatalog #M0494L
