Applications of BBa_K1489000

Expression tests BBa_K148900 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.

Clear band of correct size can be seen in the soluble induced fraction, while no band is seen in the uninduced cells.
