Biology

Mutagenesis at specific position of RBS (BBa_B0034) was achieved RBS009 (BBa_K3740008) using random primers and PCR, and the constructed plasmid J23100-RBS009-sfGFP-rrnB T1 (BBa_K3740060). Compare the fluorescence intensity of sfGFP induced by J23100-B0034-sfGFP-rrnB T1 (BBa_K3740058).

Usage

Constructed J23100-RBS009-sfGFP-rrnB T1 (BBa_K3740060) was transformed into E. coli DH5α. We quantified the fluorescence intensity when the optical absorbance of bacterial culture at 600nm was around 0.2.

Characterization

The average fluorescence intensity of sfGFP induced by RBS009 (BBa_K3740008), was less than 3% of B0034 (BBa_B0034), which means reducing the pressure to the host bacteria.
