Figure 2

Cloning of the HBV S gene and 3'-UTR in the rapid cloning vector pCR2.1. (A) An image of an agarose gel showing the MS-1-MS-2 PCR product. The * indicates the position of the PCR product. (B) An image of an agarose gel showing the supercoiled pCR2.1-HBsAg(S) and the * indicates the position of the plasmid. (C) An image of an agarose gel showing the KpnI/EcoRI digestion products of pCR2.1-HBsAg(S). The * indicates the position of the linearized plasmid and the ** indicates the position of the dropped insert. The left lane in each gel contains 1 kb DNA ladder (Promega, USA); the sizes of the respective bands is indicated on the left side of each panel.
