【摘要】 以⁵¹Cr白细胞粘附抑制(⁵¹Cr-LAI)实验为指标,研究了乙肝特异性转移因子的抗原特异性。结果表明:只有抗原特异性转移因子(TF_HBV)可以使未经免疫的鼠脾淋巴细胞对HBsAg产生LAI反应,而非特异性转移因子（TF_n）无此作用。证明TF_HBV中确含有促进抗原依赖性细胞免疫反应成分,具有抗原特异性。更多还原

【Abstract】 Antigenic specificity of specific transfer factor to hepatitis B virus (TF_HBV) had been studied by ⁵¹Cr-leukocyte adherence inhibition assay(⁵¹Cr-LAI).The present results suggested that TF_HBV could produce LAI reaction for nonimmunized mouse spleen lymphocyte on HBsAg, but non-immunized transfer factor did not. TF_HBV consist of agents of reaction that promote specific cellular immunity and have antigenic specifcity.更多还原
