Gel Purification of PCR products A~G and 1~7
PCR product of the expected size was excised from .8% agarose gel and gel purified using the Invitrogen gel purification kit. Protocol as detailed in the kit.
Second Round PCR
For stitching products A~G to 1~7. Gel purified PCR products from the above reaction were used.
