*****邵雪盈请看这*****字体要改stage one:basal experiments



As the construction and concentration of recombinant plasmid rely heavily on E.coli system in current molecule experiment protocols of Bacillus subtilis, Bacillus subtilis acts only as the secretory expression vector. Therefore, to verify the practicality of our locus and the transdermal function of recombinant transdermal protein on top of its original functions, we conducted basic experiments on E.coli to verify above assumptions.

The following figue shows the stages of our basal experiments.

① E.coli BL21 proved that the standard transdermal locus does work with GFP.

Using GFP to prove the validity of a newly designed circuit is a classical way to verify the expressing of this circuit. As expressions in E.coli involve neither secretory nor sequential problems, we hoped to verify the practicality of our locus by the expression of TD1-GFP. Thus we selected pET22b,which is a common recombinant vector for plasmid construction, as our recombinant vector and E.coli BL21 as engineered bacteria . We fused sequence TD1-GFP with T7 promoter from pET22b downstream and succeeded in expressing fusion protein TD1-GFP, induced by IPTG.



② The expression of recombinant antigen and adjuvant in E.coli BL21.

The practicality of our locus afforded by TD1-GFP enabled our to express recombinant antigen TD1-HBsAg and recombinant adjuvant TD1-LTB successfully. So far our basic molecule experiments have ended with perfection.

③ The antigenicity of the TD1-antigen(fusion protein) strongly proved our theoretical basis.

④ Verify that TD1-HBsAg is able to pass across the skin and keep its antigenicity by transdermal experiments.
