For the second condition, an ultrafiltration spin column was used to remove the entire elution buffer, and then the column was washed with column sizing buffer to remove the His-tag peptides from the membrane. The samples were stored in column sizing buffer. 2.1.5.
Adding polyhistidine tags. (A) The His-tag is added by inserting the DNA encoding a protein of interest in a vector that has the tag ready to fuse at the C-terminus. (B) The His-tag is added using primers containing the tag, after a PCR reaction the tag gets fused to the N-terminus of the gene. Visa mer A polyhistidine-tag is an amino acid motif in proteins that typically consists of at least six histidine (His) residues, often at the N- or C-terminus of the protein.
