Research Work
- Overall Description
For obtaining the signaling transduction parts of repression with high fidelity, I've experimentally designed and acquired some specific repressor-promoter pairs(R-P pairs or P-R pairs)based on Lactose Operon by directed evolution on plate. Besides, through quantitative assay,the novel artificial R-P pairs I selected have been tested for their binding performance so that P-R pairs of highest affinity and specificity can make a figure out of P-R pair candidates. Most of the parts in my work have been BioBricks-Standardized and work as BioBrick parts.
