HA proteins initially were purified using a nickel affinity column followed by anion-exchange and gel filtration chromatography
HA proteins initially were purified using a nickel affinity column followed by anion-exchange and gel filtration chromatography. assorted in potency depending on their multimeric nature and cell resource. Among the HA proteins, a high-molecular-weight oligomer elicited the strongest antibody response, followed by the trimer; the monomer showed minimal effectiveness. The coexpression of another viral surface…
