spermatozoa-coating antigen
5.The coating antigen molecules,including recombinant human augmenter of liver regeneration (ALR),double strand DNA and cardiolipin,and the coating anti-ALR antibody molecules with different status (unoxidized and oxidized antibody) were immobilized on the modified PS plates respectively and investigated by EIA. A synchronous EIA was performed to compare the results by using untreated PS plates.
7.Four recombinant proteins from different genotype and sub genotype of HEV ORF2 (452~617aa), including Burma strain from subgenotype I a (p166Bur), Pakistan strain from subgenotype I b (p166Pak), Mexican strain from genotype II (p166Mex), and US strain from genotype III (p166Us) , were used as coating antigen.
8.Offered advanced technology for diagnosis of the disease of porcine parvovirus. Based on the purified recombinant proteins, an indirect ELISA method for detection of PPV antibodies was developed. The concentration of coating antigen of NS1 is 2.69μg/ml and VP2 is 2.29μg/ml, HRP labeled anti-porcine IgG (1: 40000) being incubated at 37□ for 1h.
