1.Important assay

Hill function fitting

新しく作ったハイブリッドプロモーターに関してはデータがないので，実験によりパラメータを求める． ヒル関数をfittingさせることにより，n2,n3,K2,K3が求まる. We have obtained data for our newly devised hybrid promoter. By Hill function fitting, we have determined n2, n3, K2, and K3.

Assays for hybrid promoter

These assays were done
-to determine the characteristics of our hybrid promoter.
The data from here were used for computational analyses and simulations.

Repression and activation check with LacI and AHL

Purpose

check if AHL activates lux-lac hybrid promoter
check if lacI represses lux-lac hybrid promoter

Result & Conclusion

AND gate by AHL & IPTG
Lux-lac hybrid promoter is activated only in the presence of AHL and IPTG.

IPTG assay

Purpose

To determine the order of the concentration of IPTG necessary for the activation of our lux-lac hybrid promoter in the LacI producing pTrc99A cells.
The order of the concentration is used for more detailed assay with narrower range of the IPTG concentration.

Result & Conclusion

2.Preliminary assays

We conducted preliminary assays to practice experiments and check if the materials and methods worked properly.
