pBAD-RBS-OmpA-Bovine Galectin-1-B0012 Terminator
A fusion protein of OmpA (BBa_K1489002) fused to Bovine Galectin-1 (BBa_K1489001). Used to bind sugars at the outer cell membrane. Under pBAD regulation.
Expression Test: BBa_K1489004 was transformed into chemically competent DH5-alpha cells and plated overnight with chloramphenicol challenge. One colony was incubated in 5 mL LB media + 34 ug/mL chloramphenicol and grown to mid-log phase at 37oC. Arabinose was added to a final concentration of 0.2% to initiate protein production and cells were re-incubated at 37 oC for 21 hours. Cells were then pelleted and lysed with 10% SDS solution. Cell lysate was centrifuged at 13200 rpm in a tabletop centrifuge for 1 hour to separate soluble and insoluble fractions. Both fractions were loaded on an SDS-PAGE gel for western blot analysis using anti-His antibodies. Sequence and Features
