Description
Product Detail

This product is an 8-amino-acid hydrophilic, highly charged peptide, commonly used as a versatile fusion tag for recombinant protein purification. As one of the most widely applied epitope tags in structural and functional protein research, this short peptide tag features excellent hydrophilicity and stable charge properties, with no interference on the natural structure and biological function of target proteins.

It is specially designed for immunoaffinity chromatography purification, enabling efficient specific binding and mild elution of recombinant proteins. With reliable stability and high purification efficiency, this peptide tag is ideal for protein structural analysis, functional verification, and large-scale purification of recombinant proteins in biomedical and biochemical research.

Note: For research use only, not for clinical or human therapeutic application.
