+ | Tachystation A2(TA2) is a protein from Tachypleus tridentatus. (Horseshoe Crab Hemocyte-derived Antimicrobial Polypeptides, Tachystatins, with Sequence Similarity to Spider Neurotoxins) The paper (Directed evolution of polypropylene and polystyrene binding peptides) shows it binds to the polystyrene (PS). | ||

+ | We used it as the PS binding protein. We also inserted Superfolder GFP (sfGFP) which we improved GFP to make the folding time shorter in the N-terminal of LCI (Part: BBa_1746916). By doing so, we wanted to do the binding assay with fluorescence. | ||
+ | Moreover, we put SpyCatcher on N-terminus of sfGFP because we used the SpyTag/SpyCatcher system to bind it to other parts. | ||

+ | This part has four tags. First is 6×His-tag inserted in the N-terminus of SpyCatcher for protein purification. Second is MYC-tag inserted between sfGFP and Spy-Catcher to detect it by using the antibody. Third is a TEV protease site and we put it into two regions because it was used for protein purification in the paper (Directed evolution of polypropylene and polystyrene binding peptides/Programmable polyproteams built using twin peptide superglues). | ||

+ | We inserted it in between the BamHI site and the Ndel site on the pET11-a. We used BL21(DE3) for gene expression.We used Ni-NTA agarose for purification. After that, we confirmed the molecular weight of TA2 by using SDS-PAGE. | ||
