Usage in Band-pass Filter

This circuit is an assistant device aiming at testing the inhibition effect of C1 protein to hybrid promoter. We propose to adopt φR73δ to initiate constitutive expression of reporter sfGFP, thus construct a background with high fluorescence intensity. When C1 protein is expressed, the fluorescence intensity is supposed to go down if the inhibition circuit really works.
