Figure 6. Large scale expression of synaptogyrin 1.

Figure 6

(A) SDS-PAGE from large scale purification of synaptogyrin 1b construct 5 over-expressed in the Lemo21(DE3) strain in the presence of 250 µM rhamnose. High level expression and efficient IMAC beads binding results in a high yield of recombinantly produced synaptogyrin 1. A potential dimeric form is indicated. (B) The IMAC purified protein elutes as a single monodisperse peak from a preparative gel filtration column.
