Functional Evolution of Duplicated Odorant-Binding Protein Genes, Obp57d and Obp57e, in Drosophila
Figure 1
Expression and purification of recombinant OBPs.
Bacterial cells before (−) and after (+) induction by IPTG, and purified protein (P) were analyzed by SDS-PAGE. (A) Dmel\OBP57d, (B) Dmel\OBP57e, and (C) Dpse\OBP57de. The expected size of the expressed OBPs is about 13 kDa.
