U sing magnetic microparticle as the solid phase and europium nanoparticle as the label , a new trfia of magnetic separation was developed to detected hbsag 98 。另外,以磁性微球作为免疫反应的固相,铕纳米颗粒作为标记物,建立起固相磁分离trfia定量测定hbsag的新方法。

Now , studies on immunogenicity of hp vaccine mainly focus on oral administration with liquid or microparticles . whereas the vaccine solution administrated orally would be digested and decomposed by the low ph and pepsin . though microparticle is a popular form , it has a series of significant problems such as low encapsulation rate and possibility of antigen denaturation as a consequence of expose to organic solvents and high temperature 目前,国内外对幽门螺杆菌疫苗的研究仅局限在口服免疫,剂型以溶液或微球为主,众所周知,液体疫苗口服后易受到胃内低ph及胃蛋白酶的破坏;微球虽然是疫苗载体研究的热点,但在制备过程中应用的有机溶剂及高温操作会破坏疫苗的完整性,降低免疫效果
