Hexa-His TFA（Cat No.:I043798）is a synthetic peptide that contains a sequence of six histidine residues (His), often used in protein purification and molecular biology research. The TFA (trifluoroacetate) salt form enhances the solubility and stability of the peptide, making it suitable for laboratory applications. The Hexa-His tag binds strongly to nickel-based affinity resins, allowing for the efficient purification of recombinant proteins that have been tagged with the Hexa-His sequence. This method is widely used in protein expression, purification, and characterization, facilitating the study of proteins and their interactions in various biological systems.
