【摘要】 本文报道用小剂量完整的特异绒毛膜促性腺激素(hCG-β)作为免疫原,经过较长时间的免疫产生一系列抗血清,筛选后得到一个高滴度、高亲和力、特异性好的hCG-β抗血清,并用它建立了特异的hCG 放射免疫测定法。经600个不同样品的测定,结果证明该方法能在正常生理水平下(LH 存在下)特异地测定hCG,灵敏度较hCG/LH 放射免疫测定法提高10倍以上,为10毫国际单位/毫升(lst IRP hCG)。更多还原

【Abstract】 It is here reported that a series of hCG-specific antisera have been produceed,usingsmall doses intact subunit of hCG as an antigen,and a specific radioimmunoassay(RIA)for hCgG determination aftrer long term immunizion has been established.Results onmore than 600 different samples have shoun that the RIA can recongnize hCG at normalphysiological level of LH,and the sensitivily of this assay was ten times more than theconventional hCG/LH RIA,i.e.10 mI.U./ml(lst IRP hCG).更多还原
