HL-SAN for DNA removal in protein purification - A4
... Nucleic acids, and especially genomic DNA, often pose a problem in purification of DNA-binding proteins as they interfere with purification, downstream analysis or applications. Nucleases activity is usually difficult to remove while HL-SAN is easily inactivated or separated from other proteins. Thi ...
