乙型肝炎表面抗原 (ＨＢｓＡｇ)胶体金试剂系用 2株小鼠抗ＨＢｓＡｇ不同表位的单克隆抗体 ,一株用胶体金标记 ,并固定在玻璃纤维素膜上 ;另一株包被硝基纤维素膜作为固相。然后 ,将该两种膜分别粘贴在双面胶白色塑料垫板上 ,制成试纸条。其原理是用双抗体夹心法检测血清中ＨＢ
Hepatitis B surface antigen (HBsAg) colloidal gold reagent with two strains of mice anti-HBsAg different epitopes of monoclonal antibodies, one with colloidal gold labeled and fixed in the glass fiber membrane; the other is coated with nitro Cellulose membrane as solid phase. Then, the two kinds of film were affixed to the double-sided plastic white plastic plate, made of test strips. The principle is to use double antibody sandwich method to detect serum HB
