Expression of HCV Core Protein in E.c0fi and Its Application
Abstract: The cloned HCV core protein gene was inserted into the plasmid vector pJLA502 at EcoRI site,and the recombinant plasmid was transformed into E,coli DH_(5a),After inducing 5hrs at 42℃,SDS-PAGE analysis showed that the expressed core protein is twenty percent of total protein of E.coliDH5a;the purified core protein by Sephadex G200 gel filtration and Sepharose-4B-IgG affinity chro-matography has excellent antigenicity and specificity,and is good for detecting anti-HCV.
