pYPKa_A_ScXKS1

Plan for the construction of E. coli vector pYPKa_A_ScXKS1

Step 1 PCR of the insert

PCR with primers pfw1803 & prv1803 and template ScXKS1_template results in a 1805bp PCR product

Primers annealing on template:

Step 2 Vector digestion and cloning

Clone the PCR product in pYPKa digested with AjiI resulting in pYPKa_A_ScXKS1

Step 3 Diagnostic PCR confirmation

Confirm the structure of the pYPKa_A_ScXKS1 using primers 468, 342 and pfw1803 in a multiplex PCR reaction.

Expected PCR products sizes from 468, 342 and pfw1803 (bp):

pYPKa with insert in correct orientation: 2571, 2521
pYPKa with insert in reverse orientation: 2571, 1855
Empty pYPKa clone : 766
