3.2. ZsGreen and hRBP amplification and ligation into pQE-T
ZsGreen and hRBP genes were amplified by PCR. They were linked to linearized pQE-T vector, and the products of ligation were transformed into E.coli JM107. Recombinant vectors pQE-hRBP and pQE-ZsGreen were verified by endonucleaseBamHI.Onlytherecombinantswhoseinsertgene was oriented in the correct direction could be verified by digestion of BamHI, as described previously. The bands corresponding to the PCR products appeared. These results suggested that ZsGreen and hRBP had been cloned into the pQE-T vector in the right direction (Fig. 3A, 3B).
