HIGH LEVEL
EXPRESSION OF p24 PROTEIN OF HUMAN
IMMUNODEFICIENCY VIRUS TYPE 1 IN E.COLI |

| Abstract: | In order to study the
capsid protein (p24) of human immunodeficiency virus type 1(HIV-1),a plasmid vector
pET24,containing the p24gaq gene fragment encoding the p24 protein under the
control of the bacteriophage T7 promoter ,was constructed.The pET24 plasmid-highly
expressed a 30kDa protein of s10-p24 spanning 284 amino acid residues.The total amount of
the fusion protein was approximately 38.4% of the total celluar protein in Escherchia coli
BL21(DE3).Westein blotting and,immunodot blotting indicated that the recombinain protein
could be relognized by anti-p24 monoclonal antibody and HIV-1 positive sera
respectively.It is significance for preparing specific antibody,and diagnostic usage. |
