Description: This is the GFP DARPin in a composite part for expression of the DARPin. The promoter used in the construct is T7(Hansen et al., 2017), after that RBS sequence and then two different tags for downstream processing. The His-tag is mainly for purification and the avi-tag is for binding assays. After that the actual DARPin sequence, and then an additional His-tag and stop codon. The whole part has been ordered as one from IDT in our project and the needed restriction sites can be added on easily with overhangs in PCR. Characterization: Amplification of the part that will be integrated into the pET-Hisx6-rAPOBEC1-XTEN-nCas9-UGI-NLS plasmid. plasmid and part was digested with Xbal and NcoI. The part was ligated and transformed into BL21 expression cells. The cells were induced with IPTG, and extracted using sonication. The protein was then purified with Ni-NTA spin columns.
