In our experiment, the GADes gene from rat brain was cloned and expressed in E.coli, so as to make the recombinant GADes produced by gene technology for clinical application and further study on the relation between GAD and type 1 diabetes mellitus.Firstly, with the pUClS/GADes recombinant plasmid as template, the full-length encoding sequence of GADes was amplified by PCR, and cloned into pGEM-T vector. Secondly, the target gene was cut by EcoRI and inserted into restriction sites of pET42a vector for expression.

According to the different orientations of domain walls with respect to the (100) observation plane of a foil, 90°domain boundaries may be divided into two kinds. one is thin lens or ring shaped a-a 90°domain boundary, and the domain wall lies on the {110} plane; Usually, most of these domain boundaries are uncharged; according to the extinction rules for the (011) domain walls, the displacement vector 〓 along 〓 can be dertermined, which is parallel to the line of intersection between the domain wall and the plane consisting of spontaneous polarization vectors on both sides of domain boundary; from selected area electon diffraction of crystals including domain boundary, we not only examine slight difference in the crystal parts on both sides of the domain boundary, but also obtain crystallographic relationship between them, that is, there exists a 180°rotation symmetry operator along a normal of domain wall. The other is Z or ring shaped a-c 90°domain boundary along {010} direction, and the displacement vector 〓 runs along 〓 direction.
