Tac promoter and operator plus RBS

Tac-Promoter (abbreviated as Ptac) is a synthetically produced DNA promoter, produced from the combination of promoters from the trp and lac operons. It is commonly used for protein production in Escherichia coli

We constructed the pRead plasmid for information storage, where RSRL array and EGFP are fused downstream of this promotor. Spacer acquisition carried out by cas1/2 would cause an addition of 61 base pairs, a protospacer and another repeat sequence, thus resulting in frame shifting. In that case, the stop codon would disappear, and EGFP enter the correct reading frame.

Whenever you want to read the information, add IPTG to a final concentration of 0.5M and incubate at 20℃, leading to the expression of fluorescent protein.
