Abstract

Hemagglutinin (HA) is one of the surface antigens of virus H5N1. HA consists of two subunits HA1 and HA2. Since HA1 contains most of the surface antigenic sites of HA, it has been greatly noticed in Avian Influenza vaccine production researches. In this study, to achieve the further aim of creating vaccine against Avian Influenza A/H5N1, we purified recombinant protein - TRXHA5.1 from the observable product of gene trxha5.1 in yeast Pichia pastoris SMD1168 by affinity chromatography. The results showed that initially TRXHA5.1 has been purified successfully.
