Recombinant Dengue virus 2 Envelope protein, His-tagged
Recombinant Dengue virus 2 Envelope(aa 298-400) fused with His tag at the N-terminus was expressed in E. coli.
Envelope protein E takes part in membrane fusion between virion and host late endosomes. Virus Envelope 2 is synthesized as a homodimer with prM which plays a role as a chaperone for envelope protein E. Envelope protein E departs from small envelope protein M and homodimerizes after cleavage of prM.
The Dengue Envelope 2 protein solution (0.5mg/ml) contains 20mM Tris-HCl buffer (pH 8.0), 0.15M NaCl, 10% glycerol and 1mM DTT.
